How to remove extraneous spaces from Python array?

Question

I have a python array containing a mixed set of values that looks somewhat like the example below:

['0012 ', ' 318422 ', ' www.example.com']

My question is, how can I easily remove leading and trailing spaces from values in the array, such that it looks like this:

['0012', '318422', 'www.example.com']

Answer 1

Like so

[x.strip() for x in mylist]

Answer 2

You can use map and strip:

a = ['0012 ', ' 318422 ', ' www.example.com']
clean_a = map(lambda x: x.strip(), a)
