You have at least two problems with that code, one of which is causing
Both 'file' and 'len' are defined in the standard library, and shouldn't
be redefined in your code. And your problem is that after you redefined
'len', you then tried to use it in its original meaning.
Rename those two and you'll get further.
And it would have saved lots of time for lots of people if you included
sample data and the actual error message, marking where in your code it
occurs. Once you know it's complaining about the len() call, it's not
too hard to figure out that the problem was you rebound the len
attribute from a function to an integer.
