How to convert string to hexadecimal integer in Python?

Question

hi I get user argv from command line as follows: '0x000aff00'

and I want python to treat it as hex directly...

str = sys.argv[1]

how is it possible? thanks!

Do not make a variable name (str) that is the same as a data type (str). It's a bad thing to do. — S.Lott

Try: i = int(sys.argv[1], 16)
