how do I launch IDLE, the development environment for Python, on Mac OS 10.7?
Solution 1:
In the stock Mac OS X python installation, idle is found in /usr/bin, which is not (easily) accessible from Finder and not indexed by Spotlight. The quickest option is to open the Terminal utility and type 'idle' at the prompt. For a more Mac-like way of opening it, you'll have to create a small app or shortcut to launch /usr/bin/idle for you (an exercise left to the reader).
Solution 2:
When you open up a new terminal window, just type in
idle
Then you will see a little rocket icon show up as IDLE loads
Then the Python shell opens up for you to edit
