How can I align every word from this list?

Question

I have a list of lists in a file:

[ [ \'aaaaa\', \'bbb\',\'ccccccccc\' ], [ \'aaaaa\', \'bbbbbb\',\'cccccc\' ], [ \'aaa\', \'bbb\',\'ccccccccc\' ] ]

Answer 1

my_list = [ [ 'aaaaa', 'bbb','ccccccccc' ], [ 'aaaaa', 'bbbbbb','cccccc' ], [ 'aaa', 'bbb','ccccccccc' ] ]

# max_lengths = [max(len(y) for y in x) for x in zip(*my_list)]
# Can do above and get max lengths for each a, b, c etc but let us just get one global max for a neater solution

max_length = max(max(inner_list) for inner_list in my_list)

with open(target, "w") as writer:
   for inner_list in my_list:
       l_justed = [x.ljust(max_length) for x in inner_list)
       writer.writeline("    ".join(l_justed))

ljust adds spaces at the end to make the string length as specified value
