Python: Convert hex to string -


a value 0x0f or 0x05 has given function string without 0x @ beginning 0f or 05.

if use str(hex(0x0f))[2:4] f. crucial missing 0 still present in application.

how can that?

you'd use str.format:

in [1]: '{:02x}'.format(0x0f) out[1]: '0f'

in context {:02x} equivalent {0:02x}. preceding colon 0 tells python apply first argument of str.format (0x0f in example). 02 sets minimum field width 2 ,

preceding width field 0 ('0') character enables sign-aware zero-padding numeric types

x 1 of available integer presentation types:

hex format. outputs number in base 16, using upper- case letters digits above 9.

both quotes format specification mini-language.
