BMI Calculator Feedback

• Even if you are happy with your score, please visit Gradescope and check for any comments I might have made.

  Commits

• Commit messages pretty good.
• Some still needed a bit more detail, and so check for any comments.

  Feature Branches

• Do not make a branch from the end of a previous branch:

• Don't make any edits, including to README.md on the main branch

Modular Code

• Type conversions (int(), float()) will need to be tested in future assignments. So, do not use these functions in a function that also does I/O. Avoid:

  def get_input():
    weight = int(input("Enter Weight: "))
    return weight

• In a function that does calculations that needs to be tested, avoid calling another function that does I/O.

  def calculator():
    weight = get_input()
    weight = weight * 2.20462
    # Do other calculations here
    return answer

• Make sure a function has a return so it can be tested.

    def make_choice(input_value):
        if input_value > 0:
            print("You have a positive number.")
        elif input_value < 0:
            print("You have a negative number.")
        else:
            print("You have zero")

  Since no return, this function could not be tested. This would be better:

    def make_choice(input_value):
        answer = ""
        if input_value > 0:
            answer = "You have a positive number."
        elif input_value < 0:
            answer = "You have a negative number."
        else:
            answer = "You have zero"
        print(answer)
        return answer

Ranges

• Be careful about continuous range checking <=29.9 instead of <30
