Python For Mac

Posted on  by

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 versions of Mac OS X are similar.

I meant the one that your mac came with, but that doesn't appear to be related. The open-source Anaconda Distribution is the easiest way to perform Python/R data science and machine learning on Linux, Windows, and Mac OS X. With over 15 million users worldwide, it is the industry standard for developing, testing, and training on a single machine, enabling individual data scientists to.


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

A version of Python 2 is bundled with Mac OS X. It's fine to use that version. IDLE, Tkinter, and NumPy are part of that version, but you must download and install Pygame yourself.

Perform these steps to download and install Pygame:

  • 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 pip, the Python package manager. Enter your computer's administrator password when prompted:

  • In the Terminal window issue this command to use pip to install Pygame:

Perform these steps to test your environment:

  • In the Terminal window issue the python command. You should see something like this:

  • If you see that output, then your Python compiler/interpreter is working, and Tkinter, numpy, and IDLE are available.

  • At the Python >>> prompt, type the statement import pygame followed by the Enter key. If Python generates no error messages, then you have installed Pygame properly.

  • At the Python >>> prompt, type exit() followed by the Enter key to exit Python.

  • Close the Terminal window.


Downloading and Installing the Booksite Library

Perform these steps to download and install the booksite library:

  • Use your Web browser to download this introcs-1.0.zip file to your /Users/yourusername/Downloads directory.


    • 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.

  • In the Finder, double click on the /Users/yourusername/Downloads/introcs-1.0.zip file to unzip the file, thus creating a directory named /Users/yourusername/Downloads/introcs-1.0.

  • 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 the cd Downloads command to change your working directory to /Users/yourusername/Downloads, and then issue the cd introcs-1.0 command to change your working directory to /Users/yourusername/Downloads/introcs-1.0. (Incidentally, the cd . 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. Make sure that a file named setup.py is in your working directory.

  • Issue the python 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 python command.

  • At the Python >>> prompt, type the statement import stdio followed by the Enter key. If Python generates no error messages, then you have installed the booksite library properly.

  • At the Python >>> prompt, type exit() 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 idle 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 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 idle & to launch IDLE. Note the trailing ampersand. The trailing ampersand tells the computer to run the idleX 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 your helloworld.pyfile.

  • Issue the python helloworld.py command to run your program. If the computer writes 'Hello, World' to the Terminal window, then the execution of your helloworld.py program was successful. If the computer instead writes error messages, then use IDLE to correct your program, and issue the python 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 Finder, double-click on the /Users/yourusername/Downloads/introcs-python.zip 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.)

Then perform these steps to test your download of the booksite example programs:

  • Open a Terminal window.

  • Issue the cd Downloads and cd 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 named bouncingball.py.

  • Issue the python 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 the /Users/yourusername/Downloads/introcs-data.zip 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 Finder, double-click on the /Users/yourusername/Downloads/stdlib-python.zip 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.)

We invite you to study the code that implements the booksite library. But don't be concerned if some of the code is cryptic. The code that implements the booksite library uses some features of Python that are beyond the scope of the textbook and this booksite.


Q & A

Q. Why do I get the error ImportError: No module named stddraw when I issue the command python program_that_uses_stddraw.py?

A. You must issue the command python2.7 program_that_uses_stddraw.py, as described above.

Q. I downloaded files using my browser, but can't find them. Where are they?

A. Many browsers by default place downloaded files in the directory /Users/yourusername/Downloads.

Q. How do I break out of an infinite loop when running my program from the Terminal application?

A. Type Ctrl-c. That is, while pressing the Ctrl key, type the c key.

Q. Must I use IDLE to create my Python programs? Can I use some other text editor?

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.

    • 4.1 How to install PIP on Raspberry Pi

Python has always been known for its simplicity and ease of use. It’s like any other powerful programming language in which a programmer can use third-party libraries or frameworks to get rid of the hassle of coding from scratch.

You can find readymade libraries or frameworks on a central repository called PyPI (Python Package Index).

But the sad part is downloading, installing and managing them can be frustrating sometimes.

So this is why many Python developers depend on a special type of tool called PIP for Python to make everything much faster and easier.

What is PIP?

The term PIP stands for “Preferred Installer Program”. It’s a command line utility that allows you to install, reinstall and uninstall the PyPi packages with simple and straightforward command and that is “pip”.

So if you are already familiar with Command Prompt of windows or with a terminal or bash of Mac and Linux then you will feel right at home.

Thus we advise you to skip this portion and move right away to installation instructions of the program for the particular operating system.

But before moving further many of you might be thinking.

Does PIP comes preloaded with Python?

And the answer is if you are using Python 2.7.9 (or greater) or Python 3.4 (or greater), then yes, PIP comes preloaded with python as a default.

But if you are using some older version of Python then you have to install it by following the below mentioned instructions.

How to check if Python is Properly installed on your computer or not?

In order to check if the Python is properly installed on your device or not you have to follow up the steps below.

Important Note – The below-mentioned steps are the same for Windows, Linux, and Mac. All you need is to run Command Prompt, terminal or bash program respectively.

Type – (python --version ) and for Python 3.x users they may need to use – (python3 --version).

If you got a version number e.g. “Python 2.7.5” or any other, then it means Python is ready to go. Otherwise, you have to install Python First.

How to install PIP on Windows

In order to install PIP for Python on Windows, you need to follow the instructions mentioned below. One thing to keep in mind is that this should work for Windows 7, Windows 8.1, and Windows 10.

  • Download the get-pip.py installer script.
  • If you’re on Python 3.2, you’ll need this version of get-pip.py.
  • Open the Command Prompt and navigate to the get-pip.py file.
  • Run the following command: python get-pip.py and you are done.

How to install PIP on Mac

When it comes to installing PIP on Mac then many modern Macs comes preloaded with Python and PIP. But actually, that version of Python is a bit outdated, keeping in mind the serious Python development.

So we advise you to install the current version of Python for maximum output.

If you want to use the native Python installation but don’t have PIP available, you can install PIP with the following command in Terminal:

How to install PIP on Linux

Installing PIP on Linux Operating system is a bit different as compared to Mac and Windows. You need to check first if the Python is already installed or not.

But if your Linux distro came with Python already installed, you should be able to install PIP using your system’s package manager.

This is important because system-installed versions of Python do not play nicely with the get-pip.py script used on Windows and Mac. So keep this in mind.

Following are the commands for Different Python versions:

Should players take damage, their health meter will gradually regenerate to its halfway point. Stars displayed on the meter indicate the current wanted level. Gta 5 for mac online. If players commit crimes, law enforcement agencies may respond as indicated by a “wanted” meter in the head-up display (HUD). Players in GTA V for Mac respawn at hospitals when their health depletes. Law enforcement officers will search for players who leave the wanted vicinity.

Zypper Package Manager (Python 3.x)

sudo zypper install python3-pip python3-setuptools python3-wheel

How to install PIP on Raspberry Pi

If you own a Raspberry Pi then you must be using its official Operating system “Raspbian“.

Talking about Raspbian Jessie, then PIP comes preloaded with it as default. So this is the reason why you should shift to Raspbian Jessie instead of Raspbian Wheezy.
