Did you have a reason to spam us with a second copy of the message after
only 3 minutes? Usually, you should wait a few days, and then REPLY to
the earlier one, don't leave another with the same subject. The way you
did it, some people might respond to one, and some to the other,
creating two separate threads.

count = len(mylist)
that's all you need to count the number of items in a list.
By the way, don't ever name a variable 'list' since that's the name of
the type. It would make it hard to create a list from another type,
once you hide the definition.

l will get the values 0, 1, 2, and 3
(By the way, l is a lousy name for a variable as well, since it looks a
lot like 1)

that blows up, since you never gave tnum an initial value.

The user entered an invalid value, not between 1 and 4.

How are you going to get that 5th line, when the loop only goes around 4
times?

No clue what you're really trying to do. Maybe you should post the
exact assignment, rather than paraphrasing the teacher.
