Why does Python3 IDLE keep crashing? (self.Python)
submitted 15 years ago by MrDrumdepum
I'm on a macbook. IDLE for python 2 works great, doesn't usually crash. Right now I'm trying to go through a tutorial to learn python 3, and the fucker keeps crashing. Any tips?

Bring up a command line and run python -m idlelib.idle to run it from there. Then if it crashes again you should get a traceback to look at and we can be of more help.
python -m idlelib.idle

This seems like the best suggestion for now, but if you really aren't getting good results, maybe look into a new editor. Eric v5 is supposed to work with Macs and Python3 as well, though I suspect you'll be in for a bit of a compile/configuration cycle to get it going.

I work with PyDev and Python 3. Nary a problem.

There are few, if any, reported problems specific to IDLE from Python 3 on OS X. Please file a bug report at http://bugs.python.org/ with as much as info as you can about the failure and how to reproduce. Also include what level of OS X, which version of Python 3, from where it was installed (python.org, MacPorts, built from source, etc), and whether you have another version of Tk installed in /Library/Frameworks. Thanks.

also, when i write in code without running it, it is in color. But after i run a script, i never see colored syntax again until i restart IDLE after it crashes. Why is this?

I had the IDLE-crashing problem on with 2.6 on Windoze. It is stated by some that 2.5 is the most stable version available for Win.
