Indentation Error in Python [duplicate]
Solution 1:
You are mixing tabs and spaces.
Find the exact location with:
python -tt yourscript.py
and replace all tabs with spaces. You really want to configure your text editor to only insert spaces for tabs as well.
Solution 2:
In doubt change your editor to make tabs and spaces visible. It is also a very good idea to have the editor resolve all tabs to 4 spaces.
