Convert all strings in a list to int

Question

In Python, I want to convert all strings in a list to integers.

So if I have:

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

How do I make it:

results = [1, 2, 3] 

Answer 1

Use the map function (in Python 2.x):

results = map(int, results) 

In Python 3, you will need to convert the result from map to a list:

results = list(map(int, results))
