Hi Kamilche,
Aside from the 7bit confusion you should take a look at the 'struct'
module. I bet it will simplify your life considerably.
#two chars
>>> import struct
>>> struct.pack('cc','A','B')
'AB'
#unsigned short + two chars
>>> struct.pack('Hcc',65535,'a','b')
'\xff\xffab'
Cheers
Lars

Yep, that's what I was doing. Guess I was too tired to program usefully

At programming level it seems correct (a part a "return" closure
needed for the "main" function).
But the error is IMHO conceptual:
for a char you need 7 bits (from 0 to 127 or in hex from x00 to x7F)
and you can't accomodate the other char in only one bit!
The other 128 symbols (from 128 to 255 o

I'm trying to pack two characters into a single byte, and the shifting
in Python has me confused.
Essentially, it should be possible to use a 'packed string' format in
Python, where as long as the characters you're sending are in the ASCII
range 0 to 127, two will fit in a byte.
Here's the code.
