I don't get a TypeError, but a NameError. Reason is the line:
    filename == raw_input("Filename to load: ")
which should be:
    filename = raw_input("Filename to load: ")

After correcting this, I get the TypeError. And the error clearly says
what is wrong: in_file is a file object, and those do not have the
value "len". I think what you mean is done by replacing:
    if len(in_file) == 0:
by:
    if len(in_line) == 0:

In general, in such cases, check the error message. In this case it
said "len() of an unsized object". There is only one len() in the line
given, so that must be it, and thus in_file must be that 'unsized
object'.
