Python program to Build a Simple Calculator

print("Zero operation terminates program!") while True: o = input("Choose Operator(+, -, *, /): ") if o == "0": break if o in ('+','-','*','/'): x = float(input("Enter the value of x = ")) y = float(input("Enter the value of y = ")) if o == '+': print("%.2f" % (x+y)) elif o == '-': print("%.2f" % (x-y)) elif o == '*': print("%.2f" % (x*y)) elif o == '/': if y != 0: print("%.2f" % (x / y)) else: print("Error! Division by zero...") else: print("Invalid operator")

 

 

Output:

Zero operation terminates program!
Choose Operator(+, -, *, /): +
Enter the value of x = 12
Enter the value of y = 27
39.00

Enter the value of x = 12
Enter the value of y = 4
