The real problem is removing things from lists when you are iterating over them, not adding things to the end of lists. Python 2.7.9 (default, Mar 1 2015, 12:57:24) [GCC 4.9.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> mylist = [1,2,3] >>> for i in mylist: ... print i ... mylist.remove(i) ... 1 3 >>> mylist [2] Most people expect 1 2 and 3 to get printed, and mylist to be empty at the end of this loop.
