Top 10 Language Constructs (Phyton)

[Bruno Gustavs]

What do you think are the top ten language constructs in Phyton ?
Please don't answer in terms of OO concepts, but try to restrict
yourself to those statements you really use to cope with your
daily work.

Curious why I'm asking this question? In spite of all requirements
engineering effort we know exactly *how* to solve problems
with computer languages but know fairly, *what* we're doing
during this process.
