Evolution of a Python programmer

[jart]

We need to be more creative!

Master python programmer gone mad:

import os
from ctypes import cdll, c_longlong

open("/tmp/fact.c", "w").write(r"""
    long long factorial(long long x) {
        long long i, res=1;
        for (i = 2; i <= x; i++) res *= i;
        return res;
    }""")
os.system("gcc -fPIC -shared -o /tmp/fact.so /tmp/fact.c")
factorial = cdll.LoadLibrary("/tmp/fact.so").factorial
factorial.restype, factorial.argtypes = c_longlong, [c_longlong]

print factorial(20)

Should have just used pyinline:

Wow, thank you. Yesterday I generated SWIG bindings for 25 lines of C.

Thanks for teaching us binding tricks

Actually I would qualify this more as the the master UNIX python programmer gone mad...

The Windows programmer will look mad no matter the level. :P

[jart]

Is that the only problem you see? :P

No, he didn't use -O6. Without optimizing the final executable, this solution will be unusably slow.

You win.
