As a beginner in Python I have often found it very valuable indenting, despite the wise guide PEP8's own warnings. In the midst of learning about the amazing power shortcuts have when it comes to one's productivity, one's indentation armoury should be manned by two soldiers:

1. Ctrl + Alt + I (when indenting rightwards , i.e increasing the indentation)
2. Shift + TAB ( when indenting leftwards, i.e reducing the indentation)

I hope this helps.
