For readability purposes, you can use underscores while declaring large numbers. For example:

>>> 1_000_000_000
1000000000

>>> 0b1000_1111
143

Did you know that you can also format numbers with underscore separation?

>>> n = 14310023

# underscore separation
>>> f'{n:_}'
'14_310_023'

# you can also use comma separation for integers
>>> f'{n:,}'
'14,310,023'

Here are some examples for displaying numbers in binary, octal and hexadecimal formats:

>>> n = 14310023

>>> f'{n:_b}'
'1101_1010_0101_1010_1000_0111'
>>> f'{n:#_b}'
'0b1101_1010_0101_1010_1000_0111'

>>> f'{n:#_x}'
'0xda_5a87'

>>> f'{n:#_o}'
'0o6645_5207'

And here's an example with zero filling:

>>> for n in (3, 20, 28):
...     print(f'{n:09_b}')
... 
0000_0011
0001_0100
0001_1100
