Hey. I want to make a program like this:print "Complete the function

points for
example in f(2),f(4).. etc . How can I do this?
check out 'eval' or 'exec'.
Then check out all the reasons you shouldn't use them in an
environment that you don't trust absolutely -- if someone wipes
your hard disc, you won't get any sympathy from here.
The safe answer is to write yourself a small parser. Given that
you've got a very limited symbol set, that shouldn't be too hard.
