Hi, Im wondering how to convert a string which contains a huge integer ("10000000000007") to a real integer (type int). When I ask int() to this it replies: Traceback (most recent call last): File "C:\prime.py", line 43, in ? main() File "C:\prime.py", line 29, in main no = int( argv) ValueError: int() literal too large: 10000000000007 any ideas? TIA, Axel
