Trouble converting hex to decimal?

[Alan McIntyre]

Earl,

Try this:

 >>> ord('\x00')
0

or:

 >>> import struct
 >>> struct.unpack('b', '\x00')
(0,)

If you're needing to pull values out of multiple bytes (shorts, longs, 
floats, etc.), have a look at the struct module. Here's an example:

 >>> struct.unpack('f', '\x00\x00(B')
(42.0,)

Hope this helps,
Alan
