Convert all strings in a list to integers

How do I convert all strings in a list to integers?

['1', '2', '3']  ⟶  [1, 2, 3]

Given:

xs = ['1', '2', '3']

Use map then list to obtain a list of integers:

list(map(int, xs))

In Python 2, list was unnecessary since map returned a list:

map(int, xs)
