List of list, converting all strings to int, Python 3

Question

I am trying to convert all elements of the small lists in the big list to integers, so it should look like this:

current list:
list = [[\'1\',\'2\',\'3\'],[\         


        

Answer 1

You can use a nested list comprehension:

converted = [[int(num) for num in sub] for sub in lst]

I also renamed list to lst, because list is the name of the list type and not recommended to use for variable names.
