[Tutor] list iteration

[tpc at csua.berkeley.edu]

hi everybody,

when iterating through lists, may I assume that for all intents and
purposes, 'for item in itemslist' is the same as
'for item in itemslist[:]' ?  I first encountered the latter statement
today, and am puzzled why one would use it as opposed to the former, which
seems simpler and more straightforward.
