Convert all strings in a list to int

Question

Let's say, I have:

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

How can I change it to:

results = [1, 2, 3]

Answer 1

In the case of Python 2.x, we can use the map function

results = map(int, results)

In the case of Python 3, You actually need to convert the result from map into a list:

results = list(map(int, results))
