You define a function with: def functionName():
The body of the function should be indented (4 spaces is good).
So here are examples of 3 'stub' functions that don't do anything (yet):
# comments go after a hash
# this is the input function
varName = raw_input("Enter input: ")
# this is the conversion function
# do something here
# this is the output function
print ("You input %s" % varName)
varName = input()
if __name__ == "__main__":
You'll have to fill in the parts specific to your problem.
The best way to start is to work the problem out on paper
first: ie. you should already know how to do the math to
convert from 24 hour time, to 12 hour time. If you can't
do it on paper yet, you need to start by learning how to do it
on paper before you can teach the computer how to do it.

whole soul." [Mahatma Gandhi]
