Not sure why it didn't help you Dick, but it led me to:

http://docs.python.org/lib/typesseq.html

Which is admittedly sparing in its explanation but does at
least describe the three values involved and their defaults.

The tutorial also threw up this:

http://docs.python.org/tut/node5.html

Which describes basic slicing (using only 2 indices) of strings
and also has a link to the previous reference page.

Finally I tried googling for 'python slicing' and got this as my first 
hit:

http://docs.python.org/ref/slicings.html

Which is the language lawyers version!

HTH,
