Which is the best IDE for Python For Windows [duplicate]
I recommend you take a look at the list of editors on Python's wiki, as well as these related questions:
Python is dynamic language so the IDE can do only so much in terms of code intelligence and syntax checking but I personally recommend Komode IDE, it's pretty slick on OS/X and Windows. I've experienced high cpu use with Linux but not sure if it's caused by my VirtualBox environment.
You can also try Eclipse with PyDev plugin. It's heavier so performance might become a problem though.
