Instructions

Now is your opportunity to build a better calculator. Your calculator can work however you wish it to but it should be usable as a calculator.

Firstly, we're going to separate out of our interactive logic into the main() function, like so:

def main():
  print("Hello learners!")

if __name__=="__main__":
  main()

This is Python boilerplate code, which will only run when the program is invoked by a person. All your code should now be inside a function - either this main() function (where you can put things like input statements) or another function.

Automatic grading will be scored out of 8, and will test the functionality of the following functions:

• addmultiplenumbers([num, num, ..]) - this function must exist in your program, it should take a list of numbers as input, and it should output the sum of those numbers.
• multiplymultiplenumbers([num, num, ..]) - this function must exist in your program, it should take a list of numbers as input, and it should output the result of multiplying each number in turn with the following number.
• isiteven(num) - this function must exist in your program, it should take a single number as input, and it should output a boolean value - True if the number is an even, whole number, False otherwise.
• isitaninteger(num) - this function must exist in your program, it should take a single number as input, and it should output a boolean value - True if the number is an integer, False otherwise.

Remember This project will be automatically graded, and computers are very literal!

Note: Use the tests! There's nothing wrong with running the tests until they pass. It's not cheating!

Note: If you get stuck getting one function to work, try working on a different one. You might find you can solve later functions more quickly than earlier ones.
