class MyString:
    def __init__(self, myString):
        self.__myString = myString

    def countWord(self):
         count = len(self.__myString.split())
         return count

    def findMostFrequentChar(self):
        # ?

我需要实施findMostFrequenctChar.她给我们的唯一暗示是我们需要制作2个名单.这就是她失去我的地方.

这是调用函数的代码:

def main():
    aString = MyString("This is a super long long long string. Please help count me")
    print("There are", aString.countWord(), "words in the string.")

    count, letter = aString.findMostFrequentChar()
    print("The most frequent character is", letter, "which appeared", count, "times")

main()
