Avnit's solution was wrong. When converting a string, you
must state what base you are converting from.
>>> int(hex(m),16)
66
Fredrik Lundh's solution works if the hex string starts with "0x"
(which it will when the string is created with the hex function).
>>> int(hex(m),0)
66
But it won't work without the "0x".
>>> int('0x1A',0)
26
>>> int('0x1A',16)
26
>>> int('1A',16)
26
>>> int('1A',0)
Traceback (most recent call last):
File "<pyshell#18>", line 1, in -toplevel-
int('1A',0)
ValueError: invalid literal for int(): 1A
