How to make all lists in a list of lists the same length by adding to them

Question

I have a nested list which contains lists filled with strings. What I am trying to do is make each list in this nest the same length as the longest available list in that n

Answer 1

The problem is with the line:

if row < len(maxSS7):

You're comparing the list row with the integer len(maxSS7). It will evaluate to False each time. Change it to:

maxLen = max(map(len, myList))
for row in myList:
    if len(row) < maxLen:
        row.extend(...)
