That is still not a question.  It's a requirements statement.  I felt
tempted to point out to you that this is not a freelancer board where
you get to post your software requirements and then we go and develop
your software for you for free, but seeing as you obviously must know
this already and presumably are actually in the process of trying to
learn Python and are presumably using this apparent interview question
as an interesting learning problem, I'll instead ask you to clarify
how far you've gotten and where exactly you're stuck in developing a
solution?  We'll try and help you along and answer specific concrete
questions about problems you're having.  (Please provide code and full
error messages including stack traces where relevant.)

If you're stuck even just getting started, try breaking down the
problem into smaller sub problems and solving them first, for example
it's obvious from the descriptions you'll need to be able to:
a) Interpret command line parameters to pick up the menu file name and
products required
b) Read a/the menu file into memory
c) Perform some sort of search/scan of the list of menu items to
return a list of restaurants carrying all the required items
d) Evaluate the total costs for the items for each of the candidate
restaurants to find the cheapest one
e) Output/Print the result in the required format
Do you have an idea/know how you might tackle each of these sub-tasks?
 If not, do you have an idea where to start looking to learn what you
might use?
