I ported some Java code to Python, and it was using Java's idea of

The print statement runs twice because you're calling orderaddrtimes
twice, once for "a" and once for "b."
addrnum_dict becomes a list when you bind it to the return value from
sorted on the first call to orderaddrtimes; you get the error on the

This looks like the str (or maybe it's the repr) of an object returned

And the April issue of Compubyte (or something like that) with a cover
showing
or series of mathematical statements (no
control conditions, loops, array notation, etc.), but it would be pretty
easy to add those. It also puts too many parentheses in outputted

help(Spam1.ham).
So is there a clean way to define SpamN such that help(SpamN),
help(SpamN.ham), and help(SpamN.eggs) all do the Right Thing, and the

With all due respect, if I spent 99% of my programming time writing, I'd

really stellar compression ratios and you don't care about time to
compress, you might check out one of the many paq implementations.
