Well we don't do homework here but I can give you some pointers.

You might like to read my python tutor section on "Talking to the
User",
particularly the part on command line arguments.

Also to parse the numbers etc you migt want to look at the
string functions such as split, and concepts such as "slicing".
These are all covered in my tutor and, in much more detail,
in the python documentation.

And one last hint, look at the "in" test, as in:

if c in "+-*/=":
   # do something

HTH, Have a go, if it doesn't work come back here and ask us
some specific questions and we'll try to unravel it for you.
