There is no problem in this particular line, but you'll have plenty of
them if you'd try to use this paradigm:
blah = ((foo() and [poo()]) or [boo()])
In C, "foo() ? poo() : boo()" will not call boo() if foo() returns true;
but in Python, you'll have a side-effect of calling boo() even if foo()
returns true - what is wrong, usually.

I am. I came to Python after 10 years of Borland Pascal and no C. Firest
I tryied Perl, but was very unsuccessful writing my programs; then tryied
Python - and voila! - I use Python for over 4 years and don't see a need to
change anything! :)
I learned C after Python ('cause I switched from DOS to UNIX the same
time I turned from BPascal to Perl or Python). And still don't know much C.

Programmers don't die, they just GOSUB without RETURN.
