strip() and replace()

[Ajfaust]

#remove the whitespace characters
            i.strip()
            #remove the empty spcace
            nkeys = i.replace(' ', ',')

I'm having a bit of trouble trying to understand what's going on here. From what I understand, strip() should remove all whitespace from the string, but then you try to replace all spaces with ','s. If you just removed all the whitespace, shouldn't there be no spaces?

it should just remove the '\n',

Ah ok thanks for clearing that up

Edit: readlines returns a list of strings without '\n' though
