Hi Chappman,
Well, unless the simple formula also refers to total_prob itself, that
seems like a pretty pointless for loop, no? The variable will continually
get overwritten, and you will just end up with the value it was assigned in
the last iteration of the loop, so unless that value referred to the
previous value, it means that all the other iterations were pointless.
Anyway, the Python syntax (which is a subset of Sage syntax) for your loop
is approximately this:
for i in range(5):
for j in range(i-1):
do_something()
That's all. No "end" statements, or semicolons, or what-have-you :) Keep in
mind that indices are zero-based in Python (like C), so the first element
of a list L is L[0], and range(5) is the list [0,1,2,3,4]. By the way, this
kind of question more properly belongs in the sage-support group, rather
than the sage-devel group, which is more for discussing the development of
Sage itself.
