Question

Are there any canned Python methods to convert an Integer (or Long) into a binary string in Python?

Answer 1

I am surprised there is no mention of a nice way to accomplish this using formatting strings. TLDR:

>>> number = 1
>>> f'0b{number:08b}'
'0b00000001'

Longer story

This is functionality of formatting strings:

>>> x, y, z = 1, 2, 3
>>> f'{x} {y} {2*z}'
'1 2 6'

You can request binary as well:

>>> f'{z:b}'
'11'

Specify the width:

>>> f'{z:8b}'
'      11'

Request zero padding:

f'{z:08b}'
'00000011'

And add common suffix for binary:

>>> f'0b{z:08b}'
'0b00000011'
