I'm reading in a pickled file. The program works but I'm having

Seems to me that you have successfully found the end of file.
I'm not be facetious here. "Easier to ask forgiveness afterwards than
permission before hand" is generally (but not necessarily always) the
preferred way of coding things in Python. So instead of trying to
predict the end of file ahead of time:
while some_hard_to_calculate_condition():
do_stuff_with_pickle()
you can catch the error instead:
try:
while True: # Loop forever, until interrupted
do_stuff_with_pickle()
except EOFError:
# no more pickles, so we must be done
pass
