For now i've been trying to perform strip() on a list of strings and i did this:

i = 0
for j in alist:
    alist[i] = j.strip()
    i+=1

Is there a better way of doing that?

You probably shouldn't be using list as a variable name since it's a type. Regardless:

list = map(str.strip, list)

This will apply the function str.strip to every element in list, return a new list, and store the result back in list.
