'''Create a program that will act as a calculator. It should be able to take two values from the keyboard, accept the operation to be performed \n" + and return the computed average. We will start simple here, assuming the user just enters two integers and will just request either addition, \n" + subtraction, division and multiplication.''' def setup(message): # Give the user directions for using this program. print(message) def getInfo(): number=input("Please enter your equation: ") try: if number.count(" ") == 2: #2 spaces means three words number1,operation,number2 = number.split(" ") number1 = int(number1) number2 = int(number2) else: number1,operation = number.split(" ") number1 = int(number1) number2="" return number1,number2,operation except: return 0,0,None from math import factorial def calculate(num1,num2,op): if (op== '+'): answer = num1 + num2 elif (op == '-'): answer = num1 - num2 elif (op== '/'): answer = num1 / num2 elif (op== "*"): answer = num1 * num2 elif (op=="//"): answer = num1 // num2 elif (op=="%"): answer = num1 % num2 elif (op=="**"): answer = pow(num1,num2) else: answer = None return answer def displayResult(num1,num2,op,answer): print(f'The answer to {num1} {op} {num2} = {answer}') def detailLoop(keepGoing): while keepGoing=="T": number1,number2,operation = getInfo() if operation is None: print("This equation was not in the correct format.") else:
