Answer to Question #315355 in Python for Michael

Question

 Your younger brother is studying in school. His computer teacher gives homework to make a calculator for six operations: addition, subtraction, multiplication, division, power, and modulo on two integers. As you are about to become an engineer, so he expected help from your side to develop the program. Therefore, write Calc.py module that define a separate function for implementing all the above-mentioned operations. Then import Calc.py in your RollNo_W12A_1.py file. In RollNo_W12A_1.py, define a function Arithmatic(a, b, op) which calls the respected function defined in Calc.py to perform the required operation. Also handle the possible exceptions and display the

Answer 1

Store the following function in the Calc.py module:

def Arithmatic(x, y, op):
    """Calculator for six operations"""
    result = 0
    while True:
        if op == '+':
            result = x+y
            print(x, "+", y, "=", result)
            break
        if op == '-':
            result = x-y
            print(x, "-", y, "=", result)
            break
        if op == '*':
            result = x*y
            print(x, "*", y, "=", result)
            break
        if op == '/':
            result = x/y
            print(x, "/", y, "=", round(result, 2))
            break
        if op == '%':
            result = x % y
            print(x, "%", y, "=", result)
            break
        if op == '^':
            result = x ^ y
            print(x, "^", y, "=", result)
            break
        if op not in operations:
            print("Invalid operator")
            break

Import Calc.py module in the RollNo_W12A_1.py file using the following code:

from Calc import Arithmatic

x = int(input())
y = int(input())
op = input()
operations = ['+', '-', '^', '*', '/', '%']

Arithmatic(x, y, op)
