printing bit representation of numbers in python

Question

I want to print the bit representation of numbers onto console, so that I can see all operations that are being done on bits itself.

How can I possibly do it in pyth

Answer 1

In Python 2.6+:

print bin(123)

Results in:

0b1111011

In python 2.x

>>> binary = lambda n: n>0 and [n&1]+binary(n>>1) or []
>>> binary(123)
[1, 1, 0, 1, 1, 1, 1]
