printing bit representation of numbers in python

Question

Hi

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 python?

Thanks

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]

Answer 2

The bin function

Answer 3

This kind of thing?

>>> ord('a')
97
>>> hex(ord('a'))
'0x61'
>>> bin(ord('a'))
'0b1100001'
