I observe that your inner loop only runs to $n - 1 while in the Python script it runs to n. The former makes sense to me but the latter not. I know little about Python, but running the inner loop to n should produce no primes found at all. Why does it work anyway (I checked it does)? I guess this is off topic as it is a Python question...
