free python ide

PyCharm - https://www.jetbrains.com/pycharm/ # Only for python
Visual Studio Code - https://code.visualstudio.com/ # Personally use and can work for tons of different languages (Highly Reccommend)
IDLE # default ide comes with python, its pretty good comes with python documentation

#To be honest i personally use Visual studio code, but IDEs made by Jetbrains are also really good. They are a bit pricy though. Of course you can get to community edition as well.
'''Well, other good code editors are atom, sublime text and idle itself. By far atom is the best out of these 
However they are all text editors and not proper IDEs. 
Hope that helps.

I just use visual studio code because they are really good
It isn't an IDE but I think it's good enough for one.

I prefer Vim and Sublime text 3. Sublime text 3 is very beginner friendly. The 
UI is great and it has a lot of features. But it can't handle HUGE projects. 
That's why I recommend Vim too. Vim can be very powerfull in the right hands
and it can handle big projects with ease.
