Start up a Terminal command prompt. You can find the Terminal application through Spotlight, or navigate to Applications/Utilities/Terminal.
To start Python, type:
python
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.
>>>
note: | The >>> indicates that you are at a Python prompt. |
---|
Exit the Python prompt by typing:
exit()
Now you’re back at the OS X command prompt (which looks something like username$).
Practice these steps until you feel comfortable navigating to a command prompt, starting Python, and exiting Python.
