Python: How do I convert from binary to base64 and back?

Question

Lets say I have some binary value:

0b100

and want to convert it to base64

doing base64.b64decode(0b100) tells me that

Answer 1

Binary literals are just normal python integers.

>>> 0b100
<<< 4

>>> 4
<<< 4

Just convert to a string and base64 encode it (giving you a string that is the base64 representation of '4'). There is nothing wrong with this approach, it's lossless and simple.

>>> s = str(0b100).encode('base64')

>>> int(s.decode('base64'))
<<< 4

If you want, you can use bin to convert the int into a binary string:

>>> bin(int(s.decode('base64')))
<<< '0b100'
