I am having problem in my variable "p. Can someone help me?

Question

import random


def question1():
        print("What is the Capital of Bangladesh?")
        print("Your options are: 1)Dhaka 2)Cumilla 3)Rangpur 4)Barishal")
        # p is answer
        p = 1

def question2():
    print("Where is Bangladesh?")
    print("Your options are: 1)in Africa 2)in Asia 3)in Europe 4)in Antertica")
    # p is answer
    p = 2


n= 1
e= 5000
x= ["a","b"]

while (n==1):
    w= random.randint(0,1)
    y= x[w]
    
    if "a" in y:
        question1()
        l= int(input("Type your option number:"))
        x.remove(y)
        
        if (p == l):
            e=e*2
            print("Congrats!You have won" + e)
        else:
            print("You heve lost!")
            print("You answered" + "answers!")
            n=n+1
        
    elif "b" in y:
        question2()
        l= int(input("Type your option number:"))
        x.remove(y)
        
        if (p == 2):
            e=e*2
            print("Congrats!You have won" + e)
        else:
            print("You heve lost!")
            print("You answered" + "answers!")
            n=n+1

            
print("Your total point is:" + e)

I defined "p" variable as the answer of the MCQ questions calling a function. But inside the loop, when I call the function, the "p" variable still stays undefined. I had run that function in the loop in if statement but it seems still undefined. Why is it happening? And how to fix it?

Answer 1

Here is a version of your code that works. You had several problems. For example, this doesn't work because e is an integer, and you can't add strings and integers.

           print("Congrats!You have won" + e)

Note that I have eliminated the ["a","b"] nonsense, and have simply created a list with the question functions. Now I can choose one at random and call it, so I don't have to have a bunch of duplicated code. One chunk of code handles all the questions.

import random

def question1():
    print("What is the Capital of Bangladesh?")
    print("Your options are: 1)Dhaka 2)Cumilla 3)Rangpur 4)Barishal")
    # p is answer
    return 1

def question2():
    print("Where is Bangladesh?")
    print("Your options are: 1)in Africa 2)in Asia 3)in Europe 4)in Antertica")
    # p is answer
    return 2

n= 0
e= 5000
questions = [question1, question2]

while questions:
    question = random.choice(questions)
    answer = question()

    l= int(input("Type your option number:"))
        
    if answer == l:
        questions.remove( question )
        n += 1
        e *= 2
        print("Congrats!You have won", e)
    else:
        print("You heve lost!")
        print("You answered", n,  "answers!")
        break
    
print("Your total point is:", e)
