python错误提示ValueError: not enough values to unpack (expected 2, got 1)

Question

ValueError: not enough values to unpack (expected 2, got 1)

  File "D:\11.py", line 141, in decode
    key, value = line.strip().split('=')

改了错错了再改，能帮忙看看这又要咋解决嘞

    def encode(self):
        # 读取文章
        with open(self.filepath_entry.get(), 'r') as f:
            article = f.read()

        # 统计字符出现次数，构造编码表，并对文章进行编码
        char_count = count_character(article)
        encoding_table = build_encoding_table(char_count)
        encoded_data = encode_article(article, encoding_table)

        # 将编码表和编码结果保存到文件中
        with open(self.char_count_path.get(), 'w') as f:
            for key, value in char_count.items():
                f.write(str(key) + ',' + str(value) + '\n')

        with open(self.encoding_table_path.get(), 'w') as f:
            for key, value in encoding_table.items():
                f.write(str(key) + ',' + str(value) + '\n')

        with open(self.encoded_data_path.get(), 'w') as f:
            for code in encoded_data:
                f.write(str(code) + ',')

        tk.messagebox.showinfo('LZW编码器', '编码完成。')

    def decode(self):
        # 从编码文件中读取编码表和编码结果，并使用词典解码得到原文章
        with open(self.encoding_table_path.get(), 'r') as f:
            encoding_table = {}
            for line in f.readlines():
                key, value = line.strip().split('=')
                encoding_table[key] = int(value)

        decoding_table = {v: k for k, v in encoding_table.items()}

        with open(self.encoded_data_path.get(), 'r') as f:
            encoded_data = list(map(int, f.read().split(',')[:-1]))

        decoded_article = decode_article(encoded_data, decoding_table)

ValueError: not enough values to unpack (expected 2, got 1)
key, value = line.strip().split('=')
也就是会说line.strip().split('=')的结果没有两个值的，根据你的语句，应该是某一行不包含“=”号，指导split的结果只有一项。
很大可能是你的文件里有空行（比如文尾是空行），你可以添加判断，只有len(line.strip().split('=')) == 2的时候再赋值给key, value
