Hi Jay,

Are you sure that is what your program contained?  I'm surprised that this
didn't error out!  The program:

######
import sys
print sys[1:]
######

should raise a TypeError because 'sys' is a module, and not a list of
elements, and modules don't support slicing.  Just out of curiosity, can
you confirm that you aren't getting an error message?



(I know I'm being a bit silly about asking about what looks like a simple
email typo, but computer programming bugs are all-too-often about typos.
*grin*

When you write about a program, try using cut-and-paste to ensure that the
program that you're running is the same as the program you're showing us.)


Best of wishes to you!
