Is there a way to fix PEP-8 problems with pydev?

I want to know if there is a way to fix all PEP-8 problems automatically using the keyboard shortcut in eclipse-pydev. Googling didn't get me anywhere.

Since Pydev can detect PEP-8 problems, can they be fixed automatically?

You can activate PyDev code formatting using Ctrl+ Shift+ F(preferences in: Window> Preferences> PyDev> Editor> Code Style> Code Formatter - you can even enable it for automatic work).

, - PyDev , 100% PEP8 ( ), , , :

+14

script, autopep8 pydev , .

, - pyedit_autopep8.py( pyedit_XXXX.py). python pep8 autopep8.

eclipse pydev (at: window > preferences > pydev > scripting pydev), script location:

, autopep8, Ctrl + Shift + F python eclipse. !
