Indentation Error in Python [duplicate]

Question

I can't compile because of this part in my code:

if command == 'HOWMANY':
    opcodegroupr = "A0"
    opcoder = "85"
elif command == 'IDENTIFY':
    opcodegroupr = "A0"
    opcoder = "81"

I have this error:

Sorry: IndentationError: ('unindent does not match any outer indentation level', ('wsn.py', 1016, 30, "\t\telif command == 'IDENTIFY':\n"))

But I don't see any indentation error. What can be the problem?

Answer 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.

Answer 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.
