If you know that there will always be a trailing point, you can trim
off any trailing 0s, then trim off a trailing '.', and then cast to
int:

int(s.rstrip('0').rstrip('.'))

It'll remove only zeroes and then only periods, as opposed to
s.rstrip('.0') which would give a wrong result for (say) '40.000', so
this should be safe. If there's any non-zero digits after the decimal,
they and the decimal will be kept, which will cause the int() cast to
throw an exception.
