Boston Python Workshop 5/Friday/OSX set up Python
OS X ships with Python installed, so the goal of this page is to make sure you can start a Terminal and run Python from the command line.
- Start up a Terminal. You can find the Terminal application through Spotlight, or navigate to Applications/Utilities/Terminal.
This Terminal contains something called a command prompt. This command prompt is another way of navigating your computer and running programs -- just textually instead of graphically. We are going to be running Python and Python scripts from this command prompt. - Test your Python install at the command prompt. Type
python
and hit enter. You should see something like
Python 2.7.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>>

>>>
indicates that you are at a new type of prompt -- a Python prompt. The command prompt let's you navigate your computer and run programs, and the Python prompt lets you write and run Python code interactively.
- If the Python version number (2.7.1 in the example above) is not a number between 2.4 and 2.7 (ignoring the number after the second dot), tell a staff member.
- You just started Python! The
- To exit the Python prompt, type
exit()
and press Enter. This will take you back to the OS X command prompt.
Success!
You have tested your Python installation.
