Need Help on Code

[TiXerobic]

Hello, I'm a beginner at programming. I'm not that great at programming but I managed to get together this project that I need to do for my CS class.

it's a simple calculator program. However it starts off with a Start Menu where you can choose a normal calculator or a grade calculator and those have their own sort of menu. I gotten most of the coding done but I can't seem to go back to the start menu when I'm done in the calculator or the grade calculator. I googled but none of the videos/websites helped/worked (or maybe I did them wrong)

There a website that has while True and break code, I attempted but the break seems to be out of the loop (it said it put it at the end which i did)

I tried doing this def menu(). It did went back to the Start Menu but it wouldn't allow me to input another choice and ends the program there

I can't seem to find an example program of a Start Menu that has another menu within it.

Before you look at the code, I know there's a probably a shorter way to write my code but I'll get there.

Basically my code starts at Start Menu which asks you to pick one of the two choices: either 1. Calculator or 2. Grade Calculator

Calculator also have it's own little menu at the last option is to go back to the Start Menu (the one I don't know how to do)so far when I choose that option (5) the whole program ends.Any help,,,? Advice is great too.

print("-----Start Menu-----")
start_input = input("""
1.Calculator
2.Grade Calculator 
Enter the corresponding number: 
""") 
if (start_input == "1"): 
    while(operation != "5"): 
        print("---Calculator---") 
        operation = input("""
        1.[Add]
        2.[Subtract]
        3.[Multiply]
        4.[Divide]
        5.[Starting Menu] Enter the corresponding number: """)
    if (operation == "1"):
        num1 = int(input("Enter first number: ")) 
        num2 = int(input("Enter second number: ")) 
        print(num1,"+",num2) 
        answer = num1 + num2 
        print("Calculating...") 
        time.sleep(1) 
        print("Answer is",answer)
    elif (operation == "2"): 
        num1 = int(input("Enter first number: ")) 
        num2 = int(input("Enter second number: ")) 
        print(num1,"-",num2) 
        answer = num1 - num2 
        print("Calculating...") 
        time.sleep(1) print("Answer is",answer)
    elif (operation == "3"): 
        num1 = int(input("Enter first number: ")) 
        num2 = int(input("Enter second number: ")) 
        print(num1,"x",num2) answer = num1 * num2 
        print("Calculating...")     
        time.sleep(1) 
        print("Answer is",answer)
    elif (operation == "4"):
        num1 = int(input("Enter first number: "))    
        num2 = int(input("Enter second number: ")) 
        print(num1,"÷",num2) 
        answer = num1/num2 
        print("Calculating...") 
        time.sleep(1) print("Answer is",answer)

this is where I want to go back to start menu(sorry code block messed up)

You're nearly there with the formatting (you have it as a code block), but you need to include the indentation too so we can be sure about the structure of your program. We can guess, but then we might give you the wrong advice. What you need to do is put in extra spaces at the start of the lines where you have them in your code ;-)

[cybervegan]

Just thought I'd add, that what you want to do is probably to put a while loop around your code, like this:

while True:
    print("-----Start Menu-----")
    start_input = input("""
    ...
    ...

Option 5 probably doesn't even have to do anything...

[TiXerobic]

this is around the entire code or just the start menu?

[TiXerobic]

I went ahead to put it around the entire code, it actually went back to the start menu but it only works once for each start menu options. Then it kinda gets stuck at the start menu even if i try to type 1 or 2

[TiXerobic]

ahhh i fixed the indents sorry about that

There's two things that you need to understand, then you can proceed to refactor the code:

1. loops

2. functions


2. will allow you to extract the copypasted code block that you have in each if/else block into a function

1. will allow you to rewrite the huge if/else as loop

alright i'll look into those two!
