One and three work fine when
comparing with str values. It
is interesting that the
leading 0 on a two digit
worked. Still, one digit and
three digit work but not two.
This is now more of a
curiosity as I did use the
integer comparisons.
Emphasis on the word "seems"!
Did you try running the code provided earlier? Did you notice that such
illustrated what happens when using strings which appear as numbers, and
showed how a three digit number (expressed as a string) may well precede
a two- (or even a one-) digit number in the same form - and that the
end-result of the sequence of integers is quite-different to the
sequence of integer-values expressed as strings!
Why does this happen? Because of the way data is encoded. It is language
independent. The definition of order or sequence is called "collation".
"Comparisons" establish relative-sequence. You will find some handy
explanations of how comparisons work (eg equals or less-than) in the
Python manual.
After working through those three steps, if there's something that's
still mystifying, please refine the question...
