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]
Solution

  • 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)
