It's our _pints_ that are smaller than yours, not our ounces.

Your questions are somewhat difficult to answer because you misunderstand binary. The key is
that EVERYTHING in a computer is binary. There are NO EXCEPTIONS, it's all binary ALL the time.
The difference comes about in how this binary data is displayed and manipulated. I want to

So where do you mark the boundary between the human and the OS? If I

And you also want to see those files as containing "plain text",

Python has brought that blessing to other operating systems, as well.

With the functions 'open()' and 'read()' and 'write()'. If you're on Windows,
don't forget to include a 'b' in the mode string of the open() call, otherwise

You open the file with mode "wb" (to write binary) or "rb" (to read
binary), and then you write or read bytes (eight-bit units).

Hi there,
Lets say I want to play around with binary files in python.
Opening and using files in python is something that I think I've sort of got

The thing im wondering about is binary files.
While searching for binary and python I started reading about bin().
I can use bin() to conv
