How do I convert a hex string to an int in Python? I may have it as "
Without the 0x prefix, you need to specify the base explicitly, otherwise there's no way to tell:
x = int("deadbeef", 16)
With the 0x prefix, Python can distinguish hex and decimal automatically.
>>> print int("0xdeadbeef", 0) 3735928559 >>> print int("10", 0) 10
(You must specify
0 as the base in order to invoke this prefix-guessing behavior; omitting the second parameter means to assume base-10. See the comments for more details.)
