Setting Python 3.6.5 on the Macintosh 2 Installing Python 3.6.5 3on Macintosh 2F2, 3F Installing Python 3.6.5 4on Mac OS X is somewhat simpler than in previous years. However, packages such as numpy and matplotlib need to be installed from a networked source, just as with Windows installations. First, create a folder on your desktop — for example, Python-files — and download the fol. The only prerequisite for NumPy is Python itself. If you don’t have Python yet and want the simplest way to get started, we recommend you use the Anaconda Distribution - it includes Python, NumPy, and other commonly used packages for scientific computing and data science. NumPy can be installed with conda, with pip, or with a package manager on macOS and Linux.
As a popular open source development project, Python has an activesupporting community of contributors and users that also make their softwareavailable for other Python developers to use under open source license terms.
This allows Python users to share and collaborate effectively, benefitingfrom the solutions others have already created to common (and sometimeseven rare!) problems, as well as potentially contributing their ownsolutions to the common pool.
Install Numpy Python 3.6
This guide covers the installation part of the process. For a guide tocreating and sharing your own Python projects, refer to thedistribution guide.
Note
For corporate and other institutional users, be aware that manyorganisations have their own policies around using and contributing toopen source software. Please take such policies into account when makinguse of the distribution and installation tools provided with Python.
Key terms¶
pip
is the preferred installer program. Starting with Python 3.4, itis included by default with the Python binary installers.- A virtual environment is a semi-isolated Python environment that allowspackages to be installed for use by a particular application, rather thanbeing installed system wide.
venv
is the standard tool for creating virtual environments, and hasbeen part of Python since Python 3.3. Starting with Python 3.4, itdefaults to installingpip
into all created virtual environments.virtualenv
is a third party alternative (and predecessor) tovenv
. It allows virtual environments to be used on versions ofPython prior to 3.4, which either don’t providevenv
at all, oraren’t able to automatically installpip
into created environments.- The Python Packaging Index is a publicrepository of open source licensed packages made available for use byother Python users.
- the Python Packaging Authority is the group ofdevelopers and documentation authors responsible for the maintenance andevolution of the standard packaging tools and the associated metadata andfile format standards. They maintain a variety of tools, documentation,and issue trackers on both GitHub andBitbucket.
distutils
is the original build and distribution system first added tothe Python standard library in 1998. While direct use ofdistutils
isbeing phased out, it still laid the foundation for the current packagingand distribution infrastructure, and it not only remains part of thestandard library, but its name lives on in other ways (such as the nameof the mailing list used to coordinate Python packaging standardsdevelopment).
Changed in version 3.5: The use of
venv
is now recommended for creating virtual environments.See also
Basic usage¶
The standard packaging tools are all designed to be used from the commandline.
The following command will install the latest version of a module and itsdependencies from the Python Packaging Index:
Note
For POSIX users (including Mac OS X and Linux users), the examples inthis guide assume the use of a virtual environment.
For Windows users, the examples in this guide assume that the option toadjust the system PATH environment variable was selected when installingPython.
It’s also possible to specify an exact or minimum version directly on thecommand line. When using comparator operators such as
>
, <
or some otherspecial character which get interpreted by shell, the package name and theversion should be enclosed within double quotes:Normally, if a suitable module is already installed, attempting to installit again will have no effect. Upgrading existing modules must be requestedexplicitly:
More information and resources regarding
pip
and its capabilities can befound in the Python Packaging User Guide.Creation of virtual environments is done through the
venv
module.Installing packages into an active virtual environment uses the commands shownabove.See also

These are quick answers or links for some common tasks.
… install pip
in versions of Python prior to Python 3.4?¶
Python only started bundling
pip
with Python 3.4. For earlier versions,pip
needs to be “bootstrapped” as described in the Python PackagingUser Guide.See also
… install packages just for the current user?¶
Passing the
--user
option to python-mpipinstall
will install apackage just for the current user, rather than for all users of the system.… install scientific Python packages?¶
A number of scientific Python packages have complex binary dependencies, andaren’t currently easy to install using
pip
directly. At this point intime, it will often be easier for users to install these packages byother meansrather than attempting to install them with pip
.See also
… work with multiple versions of Python installed in parallel?¶
On Linux, Mac OS X, and other POSIX systems, use the versioned Python commandsin combination with the
-m
switch to run the appropriate copy ofpip
:Appropriately versioned
pip
commands may also be available.Download Numpy For Python 3.6 Machine Learning
On Windows, use the
py
Python launcher in combination with the -m
switch:Common installation issues¶
Installing into the system Python on Linux¶
On Linux systems, a Python installation will typically be included as partof the distribution. Installing into this Python installation requiresroot access to the system, and may interfere with the operation of thesystem package manager and other components of the system if a componentis unexpectedly upgraded using
pip
.On such systems, it is often better to use a virtual environment or aper-user installation when installing packages with
pip
.Pip not installed¶
It is possible that
pip
does not get installed by default. One potential fix is:There are also additional resources for installing pip.
Installing binary extensions¶
Python has typically relied heavily on source based distribution, with endusers being expected to compile extension modules from source as part ofthe installation process.
With the introduction of support for the binary
wheel
format, and theability to publish wheels for at least Windows and Mac OS X through thePython Packaging Index, this problem is expected to diminish over time,as users are more regularly able to install pre-built extensions ratherthan needing to build them themselves.Some of the solutions for installing scientific softwarethat are not yet available as pre-built
wheel
files may also help withobtaining other binary extensions without needing to build them locally.This page tells you how to setup a Python programming environment for your Mac OS X computer and provides a step-by-step guide for creating and running a simple 'Hello, world' Python program. All of the software is freely available on the Web. These instructions are for MacOS X 10.13 (High Sierra), but the instructions for other recent versions of Mac OS X are similar.
Overview
The Python programming environment required by this booksite consists of:
- Python, that is, the Python compiler/interpreter.
- The Python standard libraries.
- IDLE, the Python Integrated DeveLopment Environment.
- The Tkinter, NumPy, and Pygame libraries, which are used by the booksite programs that do graphics or audio processing.
- The booksite library, that is, a set of modules that we developed specifically to support this booksite.
- The Terminal application that is bundled with Mac OS X.
Downloading and Installing Python, IDLE, Tkinter, NumPy, and Pygame
Note: The Mac Finder application uses the term folder to mean a container of documents and, perhaps, other folders. This document instead uses the equivalent Unix term directory. |
![Python Python](/uploads/1/3/3/2/133277546/951362894.jpg)
Python 2 is bundled with Mac OS X. However, Python 3 is not. We recommend that you download and install Python 3, and use Python 3 exclusively when running programs associated with this booksite.
Perform these steps to download and install Python, IDLE, Tkinter, NumPy, and PyGame:
- Browse to the Python for Mac download page.
- In the resulting page click on the Download Python 3.6.5 button. Your browser will download the file
python-3.6.5-macosx10.6.pkg
to yourDownloads
directory. - Using Mac Finder Manager, navigate to your
Downloads
directory, and double-click on thepython-3.6.5-macosx10.6.pkg
file to install Python, Tkinter, and IDLE. Use the default options. (It's OK to delete thepython-3.6.5-macosx10.6.pkg
file after the installation is complete.) - Open a Terminal window. To do that, click on the Spotlight Search icon on the right end of the menu bar. (It has the appearance of a magnifying glass.) In the resulting dialog box, type
Terminal.app
followed by the Enter key. - In the Terminal window issue these commands to install NumPy and PyGame:
To 'issue a command' you should type the command followed by the Enter key. |
Perform these steps to test your installation:
- In the Terminal window issue the
python3
command. You should see something like this: - If you see that output, then your installation of Python, IDLE, and Tkinter was successful.
- At the Python
>>>
prompt, typeimport numpy
followed by theEnter
key. If no error messages appear, then your installation of NumPy was successful. - At the Python
>>>
prompt, typeimport pygame
followed by theEnter
key. If no error messages appear, then your installation of PyGame was successful. - At the Python
>>>
prompt, typeexit()
followed by theEnter
key to exit Python. - In the Terminal window issue the command
idle3
. If an IDLE window appears, then you have installed IDLE properly. Close the IDLE window. - Close the Command Prompt window.
IMPORTANT: When running the Python programs associated with this booksite, do not issue the python command. Instead issue the python3 command. The former command runs the Python 2 compiler/interpreter that is bundled with Mac OS X; the latter command runs the Python 3 compiler/interpreter that you installed by following the instructons on this page. |
Downloading and Installing the Booksite Library
Perform these steps to download and install the booksite library:
Download Numpy For Python 3.6 Macro
- Use your Web browser to download this introcs-1.0.zip file to your
/Users/yourusername/Downloads
directory. - In the Finder, double click on
/Users/yourusername/Downloads/introcs-1.0.zip
to unzip the file, thus creating a directory named/Users/yourusername/Downloads/introcs-1.0
. (It's OK to delete the/Users/yourusername/Downloads/introcs-1.0.zip
file after you have unzipped it.) - Open a Terminal window.
- At any time the Terminal application has a working directory. Initially the working directory is
/Users/yourusername
. In the Terminal window issue thecd Downloads
command to change your working directory to/Users/yourusername/Downloads
, and then issue thecd introcs-1.0
command to change your working directory to/Users/yourusername/Downloads/introcs-1.0
. (Incidentally, thecd .
command changes your working directory to the 'parent' of the current working directory.) - Issue the
ls
command to display the names of all files in your working directory. Windows startup sounds wav files. Make sure that a file namedsetup.py
is in your working directory. - Issue the
python3 setup.py install --user
command. The computer copies the files defining the booksite modules to a directory where Python can find them, and writes status messages to your Terminal window to indicate its progress.
Perform these steps to test your installation of the booksite library:
- In the Terminal window issue the
python3
command. - At the Python
>>>
prompt, type the statementimport stdio
followed by the Enter key. If Python generates no error messages, then you have installed the booksite library properly. - At the Python
>>>
prompt, typeexit()
followed by the Enter key to exit Python. - Close the Terminal window.
Configuring IDLE
So far you've downloaded and installed all of the software that you'll need. You should perform one more step before creating your first program: configure the IDLE programming environment. Follow these instructions:
- Open a Terminal window.
- In the Terminal window issue the command
idle3
to launch IDLE. - Click on the Python → Preferences.. menu item.
- Click on the General tab.
- Click on the Open Edit Window radio button.
- Click on the Ok button.
- Close the IDLE window.
- Close the Terminal window.
Composing Your First Program
Having installed Python, the Python standard libraries, IDLE, Tkinter, NumPy, Pygame, and the booksite libraries, and having configured IDLE, you are ready to compose your first Python program. Perform these instructions:
- Using the Mac Finder, create a directory named
/Users/yourusername/hello
. - Open a Terminal window.
- Issue the
cd hello
command to make the/Users/yourusername/hello
directory your working directory. - Issue the command
idle3 &
to launch IDLE. Note the trailing ampersand. The trailing ampersand tells the computer to run theidle3
program in the background, thereby leaving your Terminal application free to handle additional commands while IDLE is running. - In IDLE, type the four-line Python program helloworld.py exactly as it appears below. Use the arrow keys, mouse, or touchpad to move within the text that you have typed. Use the Delete key to delete text. Be careful; the smallest typing mistake might cause the program to fail.
- When you are finished typing, in IDLE click on the File → Save.. menu item to save the Python program. Save it in a file named
helloworld.py
in the directory/Users/yourusername/hello
. The file name is case sensitive, so make sure you use all lowercase letters.
Running Your First Program
The final step is to run your program. It is possible to run some Python programs from within IDLE, but you should run the programs associated with this booksite directly from a Terminal window. To do that, perform these steps:
- Within the same Terminal window, issue the
ls
command to display the names of all files in the working directory. Confirm that the working directory contains yourhelloworld.py
file. - Issue the
python3 helloworld.py
command to run your program. If the computer writes 'Hello, World' to the Terminal window, then the execution of yourhelloworld.py
program was successful. If the computer instead writes error messages, then use IDLE to correct your program, and issue thepython3 helloworld.py
command again. Repeat until your program runs successfully. If your program runs successfully the first time you try, then intentionally introduce an error into your program, just so you get some experience with correcting errors. - Close the IDLE window.
- Close the Terminal window.
You now have installed and configured a reasonable Python environment, and have used it to compose and run a Python program. Congratulations! You are a Python programmer!
Downloading the Booksite Example Programs (optional)
We recommend that you download the booksite example programs, that is, the example Python programs that are presented incrementally throughout the booksite. Having done so, you can run those programs to help you learn about them. Perform these instructions:
- Use your Web browser to download this introcs-python.zip file to your
/Users/yourusername/Downloads
directory. - In the Mac Finder, double-click on
/Users/yourusername/Downloads/introcs-python.zip
to unzip the file, thus creating the/Users/yourusername/Downloads/introcs-python
directory containing the booksite example programs. (It's OK to delete the/Users/yourusername/Downloads/introcs-python.zip
file after you have unzipped it.)
Epson stylus photo r285 driver download mac. Then perform these steps to test your download of the booksite example programs:
- Open a Terminal window.
- Issue the
cd Downloads
andcd introcs-python
commands to make/Users/yourusername/Downloads/introcs-python
your working directory. - Issue the
ls
command. Confirm that the working directory contains a file namedbouncingball.py
. - Issue the
python3 bouncingball.py
command. If Python launches a stddraw window showing an animated bouncing ball, then your download of the booksite example programs was successful. - Close the stddraw window.
- Close the Terminal window.
Downloading the Booksite Example Data (optional)
We recommend that you download the booksite example data, that is, the data files used by the booksite example programs that are presented incrementally throughout the booksite. Perform these instructions:
- Use your Web browser to download this introcs-data.zip file to your
/Users/yourusername/Downloads
directory. - In the Finder, double-click on
/Users/yourusername/Downloads/introcs-data.zip
to unzip the file, thus creating the/Users/yourusername/Downloads/introcs-data
directory containing the booksite example data files. (It's OK to delete the/Users/yourusername/Downloads/introcs-data.zip
file after you have unzipped it.)
Downloading the Booksite Library: Part 2 (optional)
Previously on this page we described how to download and install the booksite library so Python can find it. Now we describe how to download the booksite library so you can find it — for the sake of studying the code that implements it, should you so desire. Perform these instructions:
- Use your Web browser to download this stdlib-python.zip file to your
/Users/yourusername/Downloads
directory. - In the Mac Finder, double-click on
/Users/yourusername/Downloads/stdlib-python.zip
to unzip the file, thus creating the/Users/yourusername/Downloads/stdlib-python
directory containing the booksite library. (It's OK to delete the/Users/yourusername/Downloads/stdlib-python.zip
file after you have unzipped it.)

Q. Must I use IDLE to create my Python programs? Can I use some other text editor?
Numpy Python 3 Download
A. You need not use IDLE to create your Python programs; it is fine to use some other text editor. For example, it is reasonable to use the TextEdit editor that is bundled with Mac OS X. However if you do use some other text editor, then make sure you change its settings so it (1) uses a four-space indentation scheme, and (2) indents using spaces instead of tabs. The Wikipedia Comparison of text editors page provides summary descriptions of many text editors.
