密码猜游戏的While循环

我创建了一些功能来帮助实现4针猜游戏，并带有一个while循环，该循环告诉我不断猜测序列顺序，直到它与生成的PIN匹配为止。

import random

def genListDigits():  # No.1 Generates a list with 4 random digits between 0 and 9.
    myList = []
    for i in range(0,4):
        x = random.randint(0,9)
        myList.append(x)
    return myList

b = genListDigits()

def convertToList():  # No.2 Receives my pin and converts it into a 4-digit list.
  convertedList = []
  for s in p:
    convertedList.append(int(s))
  return convertedList

p = input("Enter a 4-PIN code: ")
a = convertToList()
print('you entered', a)

def checkNumbers(guess,right):  # #No.3 Receives both lists, compares each element in order returns a string with 4 letters stating to go higher or lower
    result = ""
    for n in range(4): 
        if guess[n] == right[n]:
          result += "Y"
        elif guess[n] < right[n]:
            result += "H"
        elif guess[n] > right[n]:
            result += "L"
    return print(result)

checkNumbers(a,b)

但是，当我添加while循环时，它似乎并没有重复执行convertToList（“输入4-PIN码：”）函数。我的while循环：

while a != b:
  q = input(convertToList())
print("Correct!")

关于如何解决这个问题的任何想法？提前致谢。
