[Tutor] Suggestions for cleaner code

Hi, I'm just learning python so my ideas might not be the best way, but I
think they might be a little cleaner than your program. I'm using the
Python for Non-programmers tutorial on the beginner's section of
www.python.org. Everything I know about python comes from there. Here is
the program I wrote after seeing your program.

def printoptions():
print "Options:"
print "1 - Greeting"
print "2 - Discussion"
print "3 - Question"
print "4 - Farewell"
selection = 67
while selection != 4:
if selection == 1:
print "Hello"
elif selection == 2:
print "I should have paid more attention in math class."
elif selection == 3:
print "Why did I sleep in math class?"
elif selection != 4:
printoptions()
selection = input("Select an option:")
print "Farewell"
One thing I noticed about your program was that it did not do (or I don't
think it does) anything if the user does not select one of the 4 choices.
This could be a problem if the user makes a typing error, or something like
that happens. If the person selects 5, I'm not sure what would have
happened in your program, but in mine, the program would reprint the
options. You might want to consider that in your future programs. Also,
what is "Core Python?"
