Hello,
I hate to ask again but i am trying to introduce a switch statement to get rid of if, else statements.
This is the original code and i would like to get rid of the if and elif. I have been reading a few posts about it saying that it is similar to switch case default in C#. But it was introduced as match case in recent versions of Python. Not so sure what to do with the implementation.
TY

# Program make a simple calculator def add(x, y): return x + y def subtract(x, y): return x - y def multiply(x, y): return x * y def divide(x, y): return x / y print("Select operation.") print("1.Add") print("2.Subtract") print("3.Multiply") print("4.Divide") while True: choice = input("Enter choice(1/2/3/4): ") # check if choice is one of the four options if choice in ('1', '2', '3', '4'): num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) if choice == '1': print(num1, "+", num2, "=", add(num1, num2)) elif choice == '2': print(num1, "-", num2, "=", subtract(num1, num2)) elif choice == '3': print(num1, "*", num2, "=", multiply(num1, num2)) elif choice == '4': print(num1, "/", num2, "=", divide(num1, num2)) # check if user wants another calculation # break the while loop if answer is no next_calculation = input("Let's do next calculation? (yes/no): ") if next_calculation == "no": break else: print("Invalid Input")I started with this :
def add(x, y): return x + y def subtract(x, y): return x - y def multiply(x, y): return x * y def divide(x, y): return x / y print("Select operation.") print("1.Add") print("2.Subtract") print("3.Multiply") print("4.Divide") # take input from the user def switch(): choice = input("Enter choice(1/2/3/4): ") # check if choice is one of the four options num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) case == "1": print(num1, "+", num2, "=", add(num1, num2)) case == "2": print(num1, "-", num2, "=", subtract(num1, num2)) case == "3": print(num1, "*", num2, "=", multiply(num1, num2)) case == "4": print(num1, "/", num2, "=", divide(num1, num2)) # check if user wants another calculation # break the while loop if answer is no next_calculation = input("Let's do next calculation? (yes/no): ") if next_calculation == "no": break else: print("Invalid Input")Any inputs on this? Not sure how to implement this.
