You have to apply rstrip to each item in the list, not the list itself.
Here are two ways to do it:
#1: modify the list in a for-loop
for i, item in enumerate(mylist):
mylist[i] = item.rstrip()
#2: make a new list with a list comprehension
mylist = [item.rstrip() for item in mylist]
Of the two, I prefer the second.
