while、if 和 for 循环。 Python上的第一个字母，最后一个字母游戏

Question

我很难弄清楚如何让它发挥作用。基本上我必须制作一个游戏，其中从 words.txt 文件中随机生成一个单词，然后交替的玩家必须键入一个以前一个单词的最后一个字母开头的单词。我想我已经掌握了它的基本原理，但有一些问题需要解决。

首先谁能告诉我为什么我的代码不起作用？当我运行它并输入一个应该完成 == True 的单词时，它似乎无法识别它。 代码如下：

import random

def dictionary_list():
    dictionary = open("words.txt","r")
    dictionary_list = dictionary.read()
    dictionary_list = dictionary_list.split()
    dictionary.close()
    return dictionary_list

def start_word(dictionary_list):
    random_number = random.randrange(0,len(dictionary_list))
    random_word = dictionary_list[random_number]
    print("Starting word: ", random_word)
    return random_word

def get_word(player_number):
    word = input(player_number)
    return word


def get_player_number(player_number):
    if player_number == 1:
        player_number = 2
    else:
        player_number = 1
    return player_number

def main():
    word_list = dictionary_list()
    starting_word = start_word(word_list)
    words_used_list = [starting_word]
    print(words_used_list)
    finished = False
    previous_word = starting_word
    count = 0
    player_number = 1
    while finished == False:
        word = get_word(player_number)
        last_letter_word = previous_word[-1]
        if word[0] != last_letter_word:
            finished == True
        elif word not in word_list:
            finished == True
        elif word in words_used_list:
            finished == True

        elif finished == True:
            print("=" * 40)
            print("Winner is player",player_number)
            print("Number of words played", count)
            print("List of words:", words_used_list)
            print("Losing word: ", word)
            print("=" * 40)
        else:
            player_number = get_player_number(player_number)
            previous_word = word
            count = count + 1
            words_used_list.append(word)

main()

问题是你有这个

 elif word in words_used_list:
            finished == True

当你的意思是：

 elif word in words_used_list:
            finished = True

（和其他 2 个地方类似）

注意你也可以说

while finished:

而不是

while finished == True:

这可能会被认为更优雅。
