Python 我的变量p 遇到问题.有人可以帮助我吗

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)

我将"p"变量定义为调用函数的McQ问题的答案.但在循环内部，当我调用函数时，"p"变量仍然未定义.我在if语句中的循环中运行了该函数，但它似乎仍未定义.为什么会发生这种事？以及如何修复它？
