I was messing with the Preferences in Python IDLE and I couldn't edit the size of the window. So I right clicked on the windows size where it says "Width and Height" and got a ridiculous size for width!
Now IDLE wont even turn on. I tried uninstalling it and installing it again but it doesn't work. I have a Mac. How do I reset IDLE?
Assuming you mean Idle (which comes with Python), close Idle, then in Terminal, type:
mv ~/.idlerc ~/.idlerc-save
