I keep getting a NameError in Python, saying that things are not defined, although I did define them

Question

So I'm creating this based of this resource, linked here: https://www.derekshidler.com/how-to-create-a-text-based-adventure-and-quiz-game-in-python/

EDIT: Here is a GitHub link to all the code: https://github.com/gabby-lucies/Quarter-1-Project/blob/master/intro.py

I'm currently stuck however, in my very first option, anytime to choose any of the options listed below, I get a NameError saying that my options are not defined. Can anyone give me any advice? Thanks! Also, sorry if this is a dumb question.

Answer 1

I've looked over your github code, so i'm changing my answer for that

After each of your option functions, you're immediately calling it, shown here

def option_animal():
    print("Seriously, you walked towards a strange animal sound just like that?")
    print("Luckily, it is only a Fwomp. It doesn't kill you, but it does glare at you strangely.")
    print("Fwomps are cute, so you want to pet it.")
    print("You also want to take the Fwomp.")
    print("You're also hungry and horrible so you also kind of want to eat the Fwomp.")
    print("What will you do?")
    print("A. Pet Fwomp B. Take Fwomp C. Eat Fwomp") 
    time.sleep(2.5)
    choice = input(">>> ")
    if choice in answer_A:
        fwomp = 1
        option_petfwomp()
    elif choice in answer_B:
        fwomp = 1
        option_takefwomp()
    elif choice in answer_C:
        option_eatfwomp()
    else:
        print(required)
option_animal()

As python is a procedural language, only the code that is before this call in the file exists, thus, at the point where you call option_animal, option_petfwomp doesn't exist, however if you remove all of these function calls and move them to the end of the file, it should work.

Hope this helps

Answer 2

Your code is not wrong, it's simply incomplete. I'm assuming you're using this to learn Python. Let me ask you a quick question. When you press run, you get some options.

What will you do?
A. Pet Fwomp B. Take Fwomp C. Eat Fwomp

If I type "A" and hit enter, it runs option_petfwomp()

But in your code you haven't defined this function.

If you add:

def option_petfwomp():
    print("option_petfwomp")

def option_takefwomp():
    print("option_takefwomp")

def option_eatfwomp():
    print("option_eatfwomp")

you'll understand how it works. Basically, you are controlling the flow of the program. If you define these functions, you can then call them from your game.

My advise:

1. Think about what you want your code to do.
2. Map it out as a diagram or psuedo-code.
3. Code it.

It seems like you copy-pasted the code, without knowing what it does, or knowing what you want it to do. That's all fine, but take time out to understand your code before hoping someone else will understand it for you.
