Hello!  What is the problem with your problem?  What have you tried?  We
will help you figure this out, but we won't do it for you.

Can you break up your problem below into conceptual steps (or pseudocode)?

"repeatedly" suggest the use of a loop.  Perhaps a "while True:"?

"the user enters done" suggests using a conditional statement to check for
whatever you have the user to enter to indicate done, perhaps a "q" for
quit.  So perhaps something like "if user_input == 'q':" then "break" out

What Python statement can you use to collect "input" from the user?  What
will be the data type of the user input?  Will you need to convert it?
What Python statements will do the conversion?

How will you determine if the number is valid?  Hints:  Try in the
interpreter "int('a')".  What happens?  Do you get an exception?  If yes,
how can you use that in a try/except structure?

What data structure will you store all of the correctly entered numbers
into?  Does that data structure have a convenient method for determining
the minimum/maximum values contained in that structure?

Hopefully there are enough hints to get you to the point of writing some
code.  Suggestion:  Write out the steps the program must perform in the
correct order in natural language and see if you can translate that process
of ordered steps into Python.

Good luck!  If you run into problems copy-and-paste your code into a plain
text email along with the copy-and-paste of any tracebacks and someone will
