python "jump" or "goto" commands?

Nope. _Technically_, the bytecode support is available (because it's
necessary for some other constructs), but there is no way to emit that
bytecode in Python code. The chance that Python will ever grow a 'jump' or
'goto' statement are about as slim as the chance that the entire Python
development team, the PSF and the leftovers of the Python consortium get hit
by a bus in the same day (or, more likely in some of the cases, intoxicated
beyond all recognition within reach of a terminal which happens to be logged
into SourceForge, also all in the same day.)

In Python, you can use a try/except or try/finally block, and raise an
exception, to fake a goto. That's usually the way used to break out of
several layers of loops in an ugly way. I personally find that my code is
doing the wrong thing when I find I need that, though, and a bit of
re-structuring leaves the code overall shorter, faster, cleaner, and without
such hacks :)

Most programmers use an 'if' statement for that, possibly combined with
functions :)
