So I'm trying to run a unit test, and here is how far i've got. Unfortunately I get this error:

TabError: inconsistent use of tabs and spaces in indentation
n160-p132:A SahandZarrinkoub$ python3 unittest.py
  File "unittest.py", line 121
    self.atomlista = data.split(";") 

and i can't figure out why. I've checked all the tabs, spaces etc in the document.

Thankful for any help.

Answer 1

I found out I had in fact some indentations in my code consisting of spaces rather than tabs. My editor had a function for finding these groups of spaces and replacing them with tabs, which solved the problem.
