130 – Make numbers more readable

You can use the character underscore _ in number literals (integers, floats, and complex numbers), to separate groups of digits. This works for any base that Python supports:

• grouping digits by thousands in base 10;

• grouping bits by 4 or 8 bits in base 2; and

• grouping RGB channels in colours represented in hexadecimal,

are just some examples:

x = 12_345_678  # integer
almost_x = 12_345_677.99  # float
complex_x = 1+23_456j  # complex

binary = 0b1110_0100
octal = 0o7351_2242
hexadecimal = 0xff_d3_ab
