Python Hexadecimal
Use the format()
function with a '02x'
format.
>>> format(255, '02x')'ff'>>> format(2, '02x')'02'
The 02
part tells format()
to use at least 2 digits and to use zeros to pad it to length, x
means lower-case hexadecimal.
The Format Specification Mini Language also gives you X
for uppercase hex output, and you can prefix the field width with #
to include a 0x
or 0X
prefix (depending on wether you used x
or X
as the formatter). Just take into account that you need to adjust the field width to allow for those extra 2 characters:
>>> format(255, '02X')'FF'>>> format(255, '#04x')'0xff'>>> format(255, '#04X')'0XFF'
