What do you mean 'binary numbers'? They are all binary. If you mean the
int type, they are 32 bits long and there are 16 bits between the MSB
and LSB (Most/Least Significant _B
Hi there,
I'm trying to switch binary numbers around so that the MSB becomes the
LSB etc. Is there an easy way of doing this as I can't seem to find
anything. If you could help that would be great. Thanks and good
luck.

Don't know if this is what you mean, but:
Binary to decimal:
>>> bin_num = '11011'
>>> int(bin_num, 2)
267
>>> def dec2bin(dec_number):
... if dec_number == 0: return '0'
... return (dec2bin(dec_number >> 1) + str(dec_number % 2))
...
>>> dec2bin(267)
'011011'

This is a popular topic in the Python Cookbook, maybe one of these recipes will
suit you:

Hi !
How to work with binary numbers in python ? Is there a way to print a number
in its binary form like we do with oct() or hex() ?
Im doing a project that i have to work with binaries and i tired of convert
numbers to string all the time to perform some operations.
