The most common other way that I use it is on Windows. If you want the
terminal to stay open after your program has finished executing you can do
something like this:
# print_odds.py
# Prints some odd numbers
for x in xrange(1, 20, 2):
print x
raw_input("Press <enter> to continue")
I've done similar things when debugging in a loop - instead of using print,
I use raw_input and it lets me see the output and waits for me to hit enter
to continue the loop.
