Converts the character type in list to an integer

Question

I have these data to convert it to integers.

['8737', '5330', '7463']
['690', '7227']
['4043', '1572']
['8334', '3227', '5642']
['3705', '3522']

I use enumerate to finish it:

for index, item in enumerate(list_a):
list_a[index] = int(item)

Is there other ways to finish it ?I try sting.atoi() to make it ,but it can only converts string to integer.

Answer 1

Sure, you can use map for this.

list_a = list(map(int, list_a)) .
