Possible mixed indentation in Python?

Question

Looking at this question, I tried OP\'s the code on my machine. Here are a text version and a screenshot:

Answer 1

Easy!

def square(x):
    runningtotal = 0
    for counter in range(x):
        runningtotal = runningtotal + x
return runningtotal

First, tabs are replaced (from left to right) by one to eight spaces such that the total number of characters up to and including the replacement is a multiple of eight <...>

So this tab at the last line is replace with 8 spaces and it gets into the loop.
