Python-list Digest, Vol 170, Issue 34

[ROGER GRAYDON CHRISTMAN]

I'll answer your question with a couple questions:

Why do you expect to get the results you seem to expect?

What part of your code should repeat (and why)?

A key factor in recognizing the difference between 'if' and 'while'
is knowing what effect they have on the indented statements 
that follow them.
