Not sure about that. Might as well be to make it a bit more difficult.

Quote:I'm not a Python expert, but if you amend the third line of your program to test that the last digit of s is not zero, it will return Valentin's original 37 numbers (at some cost in execution speed).

Or then you simply filter them out after the computation:
Code:
python selfie.py | grep -v ^0
