Decorating Hex function to pad zeros

Question

I wrote this simple function:

def padded_hex(i, l):
    given_int = i
    given_len = l

    hex_result = hex(given_int)[2:] # remove \'0x\' from beginning o         


        

Answer 1

Suppose you want to have leading zeros for hexadecimal number, for example you want 7 digit where your hexadecimal number should be written on, you can do like that :

hexnum = 0xfff
str_hex =  hex(hexnum).rstrip("L").lstrip("0x") or "0"
'0'* (7 - len(str_hexnum)) + str_hexnum

This gives as a result :

'0000fff'
