ASSIGNMENT

You are going to enhance the prior assignment by doing the following.

• Move all the def functions into W5_firstname_lastname_Mylib.py
• Use import to include W5_firstname_lastname_Mylib into the code
• Test the code and make sure that the prior code is still working (Create your own application/test in the program using the library)
• Add the following function into Mylib (see attached video from week3 for hints)

    scalc(p1)

    p1 will be a string like this "N1, N2, operator"

   examples

    scalc("20,30,*")

    the result will be 600

    scalc("50,20,+")

    the result will be 70

    scalc("50,20,-")

    the result will be 30
    scalc("60,20,/")

    the result will be 30

• Use string functions to parse the first number, the second number, and the operator from the input string.
• Use the prior functions (add, subtract, divide, and multiply) to do the calculations.
• Do not use any UI functions in the library such as print(), input(), and format. A function should accept a parameter and return at least one value to the caller. 

Submission Instructions:

Make sure that you save your code as text in this format.
