        return diction

def max_word(diction):
        for n,c in diction.items():
            if(c==max(diction.values())):
                return n

if __name__=='__main__':
    word = input()
    c = count_word()
    d = c.count(word)
    print(max_word(d))

Solution:
class Book:

        self.bookId = bookId
        self.bookName = bookName


class Library:
    def __init__(self, libId, address, bookList):
        self.libId = libId
        self.address = address
        self.bookList = bookList

    def count_book(self, char):
        count = 0
        for i in bookList:
            if (i.bookName[0] == char):
                count = count + 1
            return print(count)

    def remove_book(self, books):
        for j in bookList:
            if j.bookName not in books:
                print(j.bookName)


if __name__ == '__main__':
    count = int(input())
    bookList = []
    for i in range(count):
        bookId = input()
        bookName = input()
        bookList.append(Book(bookId, bookName))
    libId = input()
    address = input()
    lib = Library(libId, address, bookList)
    char = input()
    books = []
    cnt = int(input())
    for j in range(cnt):
        books.append(input())
    out1 = lib.count_book(char)
    lib.remove_book(books)
