Now, how does it go ...

#!/usr/bin/env python

_pc = 1
while True:
    if _pc == 1:
        # statement 1
        _pc = _pc + 1
    elif _pc == 2:
        # statement 2
        _pc = _pc + 1
    elif pc == 3:
        # statement 3
        _pc = 17       # GOTO 17
    elif pc == 4:
        # statement 4
        _pc = _pc + 1
    ...
    else:
        # Fallen off the end of our program.
        break
