我正在尝试通过使用函数使我的代码更简洁高效

Question

我的代码工作正常，但我肯定有不必要的重复代码。我想使用函数，所以我没有重复的代码。对于如何使我的密码生成器代码更简洁的任何建议，我将不胜感激。

我尝试浏览其他论坛，但找不到所需的答案。

import string
import random
lowerCase = string.ascii_lowercase[:26]
upperCase = string.ascii_uppercase[:26]
numberList = ["1","2","3","4","5","6","7","8","9"]
specialCharacters = ["*","&","@","!"]
responseList = ["weak","medium","strong"]
randomCharacters =[ ]
i=0

while True:
  choice = input("Want to create a password? To make your choice for your password strength, please respond with one of the following: weak/medium/strong. ")

  if choice in responseList:
    if choice == "weak":
      while i<=5:
        randomLetterLower = random.choice(lowerCase)
        randomCharacters.append(randomLetterLower)
        i += 1

    elif choice == "medium":
      while i<=4:
        randomLetterLower = random.choice(lowerCase)
        randomCharacters.append(randomLetterLower)
        randomLetterUpper = random.choice(upperCase)
        randomCharacters.append(randomLetterUpper)
        i += 1

    elif choice == "strong":
      while i<=1:
        randomLetterLower = random.choice(lowerCase)
        randomCharacters.append(randomLetterLower)
        randomLetterUpper = random.choice(upperCase)
        randomCharacters.append(randomLetterUpper)
        randomNumber = random.choice(numberList)
        randomCharacters.append(randomNumber)
        randomSpecialCharacter = random.choice(specialCharacters)
        randomCharacters.append(randomSpecialCharacter)
        i += 1

    output = " ".join(randomCharacters)
    print(output)
    i = 0
    randomCharacters =[]

  else:
    break

输出实际上可以找到并得到我想要的东西。
