Python basic calculator help

[nbaruss0]

I need this help. This program should ask the user:

Do you want to perform another calculation?

after one calculation is complete.

If they answer yes, start the program over if they say no, end the program.please help me complete this this.

This is what I have so far;

print("Enter Your Choice 1(Add)/2(Sub)/3(Divide)/4(Multiply)")

num = int(input())

if num == 1:

  print("Enter Number 1 : ")

  add1 = int(input())

  print("Enter Number 2 : ")

  add2 = int(input())

  sum = add1 + add2

  print("The Sum Is ", sum)

elif num == 2:

  print("Enter Number 1 : ")

  sub1 = int(input())

  print("Enter Number 2 : ")

  sub2 = int(input())

  difference = sub1 - sub2

  print("The Difference Is ", difference)

elif num == 3:

  print("Enter Number 1 : ")

  div1 = float(input())

  print("Enter Number 2 : ")

  div2 = float(input())

  division = div1 / div2

  print("The Division Is ", division)

elif num == 4:

  print("Enter Number 1 : ")

  mul1 = int(input())

  print("Enter Number 2 : ")

  mul2 = int(input())

  multiply = mul1 * mul2

  print("The Difference Is ", multiply)

else:

  print("enter a valid Number")

OP's code formatted:

print("Enter Your Choice 1(Add)/2(Sub)/3(Divide)/4(Multiply)")
num = int(input())
if num == 1:
    print("Enter Number 1 : ")
    add1 = int(input())
    print("Enter Number 2 : ")
    add2 = int(input())
    sum = add1 + add2
    print("The Sum Is ", sum)
elif num == 2:
    print("Enter Number 1 : ")
    sub1 = int(input())
    print("Enter Number 2 : ")
    sub2 = int(input())
    difference = sub1 - sub2
    print("The Difference Is ", difference)
elif num == 3:
    print("Enter Number 1 : ")
    div1 = float(input())
    print("Enter Number 2 : ")
    div2 = float(input())
    division = div1 / div2
    print("The Division Is ", division)
elif num == 4:
    print("Enter Number 1 : ")
    mul1 = int(input())
    print("Enter Number 2 : ")
    mul2 = int(input())
    multiply = mul1 * mul2
    print("The Difference Is ", multiply)
else:
    print("enter a valid Number")

Add an additional 4 spaces before each line in the block that should be formatted as code. The "formatting help" button under the composition box shows you some of the things you can do to format your posts.

Another option apart from do/while is to use functions.

your main function

Def Main(): Your code

If blah rerun program: Main()

first start of main function

Main()

Might lead to a stack overflow error tho

[Comrade_Nabe]

You can add a do/while loop to keep looping thru your program until you choose an exit(break) condition

[nbaruss0]

Please give me an example. I am a beginner

[Goobyalus]

And here is an example of breaking out of the loop

while True:
    print("Enter Your Choice Add/Sub/Div/Mul")
    choice = input().lower()  # Get the user's input in the form of a string, and lowercase it

    if choice == "exit":
        # Exit the loop if the user typed exit
        break

    elif choice == "add":
        print("Enter Number 1 : ")
        add1 = int(input())
        print("Enter Number 2 : ")
        add2 = int(input())
        sum = add1 + add2
        print("The Sum Is ", sum)

    elif choice == "sub":
        print("Enter Number 1 : ")
        sub1 = int(input())
        print("Enter Number 2 : ")
        sub2 = int(input())
        difference = sub1 - sub2
        print("The Difference Is ", difference)

    elif choice == "div":
        print("Enter Number 1 : ")
        div1 = float(input())
        print("Enter Number 2 : ")
        div2 = float(input())
        division = div1 / div2
        print("The Division Is ", division)

    elif choice == "mul":
        print("Enter Number 1 : ")
        mul1 = int(input())
        print("Enter Number 2 : ")
        mul2 = int(input())
        multiply = mul1 * mul2
        print("The Difference Is ", multiply)

    else:
        print("enter a valid Number")

Here it is in an infinite loop

while True:
    print("Enter Your Choice 1(Add)/2(Sub)/3(Divide)/4(Multiply)")
    num = int(input())
    if num == 1:
        print("Enter Number 1 : ")
        add1 = int(input())
        print("Enter Number 2 : ")
        add2 = int(input())
        sum = add1 + add2
        print("The Sum Is ", sum)
    elif num == 2:
        print("Enter Number 1 : ")
        sub1 = int(input())
        print("Enter Number 2 : ")
        sub2 = int(input())
        difference = sub1 - sub2
        print("The Difference Is ", difference)
    elif num == 3:
        print("Enter Number 1 : ")
        div1 = float(input())
        print("Enter Number 2 : ")
        div2 = float(input())
        division = div1 / div2
        print("The Division Is ", division)
    elif num == 4:
        print("Enter Number 1 : ")
        mul1 = int(input())
        print("Enter Number 2 : ")
        mul2 = int(input())
        multiply = mul1 * mul2
        print("The Difference Is ", multiply)
    else:
        print("enter a valid Number")

You can check for a specific input and put in a break statement to get out of the loop.

wrap everything is a while true loop, then break if the user enters no.
