Remove items from a list while iterating in Python

I'm trying to remove an item from a list in python:

x = ["ok", "jj", "uy", "poooo", "fren"] for item in x:     if len(item) != 2:         print "length of %s is: %s" %(item, len(item))         x.remove(item) 

But it doesn't remove "fren" item. Any ideas?

You can't remove items from a list while iterating over it. It's much easier to build a new list based on the old one:

y = [s for s in x if len(s) == 2]
