How to convert strings into integers in Python?

Question

I have a tuple of tuples from a MySQL query like this:

T1 = ((\'13\', \'17\', \'18\', \'21\', \'32\'),
      (\'07\', \'11\', \'13\', \'14\', \'28\'),
               


        

Answer 1

I would rather prefer using only comprehension lists:

[[int(y) for y in x] for x in T1]
