You received more data than you sent? That should never, ever happen.

You can do anything you want with the data. It's a Python string. A python
string is a list of characters (bytes), which for practical purposes is
pretty much an array of 8-bit bytes. If you want to send things other than
text strings, I suggest using
1) The struct module to pack/unpack data using known binary layouts.
2) Something like the pickle module to serialize Python objects.
