  • You are using the wrong terminology here. Hex is a base 16 numerical notation, base 2 is binary. You are instead trying to format hexadecimal to using 2 digits, padding with zero as needed.

  • @GuiLuiz You mean converting binary (base 2) to hex (base 16) ?

Because hex produces a string, you can just parse the string after conversion to hex.



leading_zeros = 2

str_hex = hex(int('110', 2))
final_hex = '0x'+str_hex[2:].zfill(leading_zeros)



As pointed out by Martijn Pieters in the comments, the much better solution is to use Pythons built in format function.



format(5, '#04x')

    The correct solution is to not use the hex() function to begin with. format(value, '#04x') would give you the correct format without string concatenation and str.zfill() calls.
