You followed the OP into using "pop" as a name for an instance.
However "pop" is also a *method* of type list. While it's not as bad
as for example using the name "str" for a string ("str" is a build-in
function which is not reachable anymore if it's name is used this way)
this still makes my spider sense tingle. Whether it's because you
failed to mention this or just because it's dialectical I don't know
:-)
