🔒 Using continue for specific part of loop - Beginner

[dry lance]

So as I'm trying to improve my calculator program after every result I ask the user if they would like to use the calculator. Now I've created a condition if they say Y it would repeat the process. However at the bottom I added != "N" for any other respose other than Y or N. Outside the following code I provided there is another while loop which takes the response of N and stops the program.

But my question is, for the last elif condition, how can I create a loop where if the user doesn't type either Y or N it would keep asking again? I tried continue but that would start the whole program (the loop outside the code I provided.)

if operator == "Multiply":
            multiply = number_One * number_Two
            print("Answer:", multiply)
            restart = input("Would you like to continue (Y/N)? ")
            if restart == "Y":
                continue
            elif restart != "N":
                print(
                    "That's not one of the options. Please type in Y for (Yes) or N for (No)"
                )```

One possible solution is a while loop that keeps prompting the user to type in Y or N until the user inputs one of those letters

[dry lance]

So another while loop in a while loop?

[long void]

whats the variable that holds the users answer

[dry lance]

multiply = number_One * number_Two

[long void]

hrm

wait i think i see it, its restart

[dry lance]

I just answered you with that question

How is it restart

[long void]

okay so if you do while restart not Y or N "whatever is is you want to do"

[long void]

restart is the variable that holds the users yes or no answer

as seen by restart = input()

[dry lance]

Would the condition in this while be

while (restart != "Y") or (restart != "N")```

[dry lance]

Yes for that one yea

[minor meteor]

Yeah that looks good

[dry lance]

Let me give it a shot

[long void]

thats basically what i just says this is so sad

[dry lance]

My bad 😔

[long void]

all good lol i can barely ever understand myself, no reason i should expect anyone else to

[dry lance]

Lol it is okay

@minor meteor Seems to work. Thanks for the answer

I wrapped the while around the Y/N question specifically

[minor meteor]

Nice

[dry lance]

Also another question

while (restart != "Y") or (restart != "N"):```

is the condition here suppose to be or or and

Or is it that either could work

[minor meteor]

or

[pine aurora]

can restart be both "Y" and "N" at the same time?

[minor meteor]

You can try and, I'm pretty sure that loop would be never stop (or start? idk my brain isn't braining right now)

[dry lance]

That made sense lol

Thanks again

Wait that didn't work lol

Came back to the same issue again

if operator == "Divide":
            if number_Two == 0:
                print(
                    "You cannot divide by 0. Start the program again if you would like to try again.clear"
                )
                exit()
            divide = number_One / number_Two
            print("Answer:", divide)
            
            while (restart != "Y") or (restart != "N"):
                restart = input("Would you like to continue (Y/N)? ")
                if restart == "Y":
                    continue
                elif restart != "N":
                    print(
                        "That's not one of the options. Please type in Y for (Yes) or N for (No)"
                    )```

The loop in the second while when the user types Y repeats the same question again

@minor meteor

[minor meteor]

Oh you might want break

instead of continue

Or wait hold on

[dry lance]

Wouldn't break "break" out of the loop and move to the enxt line

[minor meteor]

You don't need if restart == "Y" anymore

[minor meteor]

Isn't that what you want? I can't tell without seeing the full code

[dry lance]

Just that line or with the continue below it too

[dry lance]

Let me share it hold on

[minor meteor]

continue too

[dry lance]

Here's the complete code:
https://pastebin.com/VNLfBG7D

In case you're wondering what's menu_select it's just choosing between calculator and other apps that I made

So don't want to confuse on that

[minor meteor]

I think this makes more sense:

            
            restart = input("Would you like to continue (Y/N)? ")
            while (restart != "Y") or (restart != "N"):
                
                restart = input(
                        "That's not one of the options. Please type in Y for (Yes) or N for (No)"
                    )```

[dry lance]

Oooh

[minor meteor]

Oh wait I forgot the input inside the loop

[dry lance]

Then the if statement = Y would be outside and underneath while yea?

[minor meteor]

There I edited it

[minor meteor]

I'm not sure what you're asking

[dry lance]

Based on what you gave me there is no program that will recognize if the user has inserted Y

Or will While automatically recognize that

[minor meteor]

I forgot it, I have now edited it

[lament sage]

Do you guys need help?

[dry lance]

This code seems to be missing something lol

Isn't restart suppose to be within while

Because right now it's just infinitly asking the question whether you write Y or N

[minor meteor]

By the way, your main while loop (at the very top) is:
while restart != "no": operator = (
and you're asking for "N"

you're typing lowercase y and n

Right now your code is case sensitive

[dry lance]

Ah you didn't add it my bad lol

[minor meteor]

If you want to make it case insensitive, you can use
restart = input("...").lower()

[dry lance]

Yea but doesn't that mean as long it's not "N" the loop will run. Once the user says "N" as in they don't want to continue they'd get out of the program

[dry lance]

I use .title().strip()

[minor meteor]

That's at the top, not at the inner loop, right?

[dry lance]

Yea

[minor meteor]

So the inner loop is still case sensitive

[dry lance]

Right

Let me try now that I've fixed that

[dry lance]

inputs are ended with .title().strip()

[minor meteor]

Show inner loop code again?

[dry lance]

so cace sensitive shouldn't be an issue

if operator == "Divide":
            if number_Two == 0:
                print(
                    "You cannot divide by 0. Start the program again if you would like to try again.clear"
                )
                exit()
            divide = number_One / number_Two
            print("Answer:", divide)
            
            restart = input("Would you like to continue (Y/N)? ").title().strip()
            while (restart != "Y") or (restart != "N"):
                
                restart = input(
                        "That's not one of the options. Please type in Y for (Yes) or N for (No)"
                    ).title().strip()```

[minor meteor]

yeah there's a problem with the loop condition

it's always True

[dry lance]

It's funny we went from it was never looping to now it's looping forever

[minor meteor]

lol

Do you know lists?

[dry lance]

Not yet

My next lesson is libraries tho

Dw it is not a class lesson or anything

[minor meteor]

I'm thinking about how to fix the loop without it being messy

[dry lance]

Technically speaking if I knew def by now the code would've been a lot shorter. But it's messy for now. As I'm learning I'm updating my code with it so

Messy for now is fine

[minor meteor]

while not ((restart == "Y") or (restart == "N")):

Messy but I think it should work

[dry lance]

Wait what's not

Isn't that the same as !=

[minor meteor]

!e

print(not True)
print (not False)

[lyric lantern]

:white_check_mark: Your 3.12 eval job has completed with return code 0.

001 | False
002 | True

[dry lance]

while not ((restart == "Y") or (restart == "N")):

while (restart != "Y") or (restart != "N"):```

Explain me the difference lol

[lean axle]

while restart != "Y" and restart != "N":```or (but a bit more advanced if they don't know lists and tuples) ```py
while restart not in ("Y", "N"):```

[dry lance]

The second one looks like range

[minor meteor]

Oh yeah that's better

[dry lance]

Soo

Which one are we picking

[minor meteor]

The first one

[dry lance]

while restart != "Y" and restart != "N":

This?

[minor meteor]

Yes

[dry lance]

I asked earlier with and and you said restart cannot be Y and N at the same time lol

Just want to make sure

[minor meteor]

Hmmm yeah that's my mistake, sorry

[dry lance]

No worries

Fixed

Thank you for the help

[minor meteor]

No problem!

[dry lance]

Uhum Annoying but one last question lool

At the moment when the user types N the only way to exit the code is typing exit()

[minor meteor]

As an input?

[dry lance]

Yea so like

if operator == "Multiply":
            multiply = number_One * number_Two
            print("Answer:", multiply)

            while (restart != "Y") or (restart != "N"):
                restart = input("Would you like to continue (Y/N)? ")
                
                restart = input("Would you like to continue (Y/N)? ").title().strip()
            while restart != "Y" and restart != "N":

                restart = (
                    input(
                        "That's not one of the options. Please type in Y for (Yes) or N for (No)"
                    )
                    .title()
                    .strip()
                )
                exit()

        if operator == "Divide":
            if number_Two == 0:
                print(
                    "You cannot divide by 0. Start the program again if you would like to try again.clear"
                )
                exit()
            divide = number_One / number_Two
            print("Answer:", divide)

            restart = input("Would you like to continue (Y/N)? ").title().strip()
            while restart != "Y" and restart != "N":

                restart = (
                    input(
                        "That's not one of the options. Please type in Y for (Yes) or N for (No)"
                    )
                    .title()
                    .strip()
                )
                exit()```

Top multiply bottom divide

I was wondering

Why not just type exit() once at the very end

Is that possible?

[minor meteor]

I think so

[dry lance]

Yea cuz you know they say

Less lines better, and I want to get used to that

Because right now if I don't type exit() but run the loop with N it keeps asking the question again
