获取类型错误：|= 的不支持的操作数类型：尝试运行脚本时出现“str”和“bool”消息

Question

我有一个 python 脚本，我试图确定 json 格式的 .txt 文件是否返回正数或负数以包含某些语句。一些示例语句是：“高曝光率”、“网络钓鱼和其他欺诈”、“可疑内容”。在确定每个 .txt 文件返回正数还是负数后，脚本应该将结果写入 csv。我正在尝试处理大约 100,000 个 .txt 文件。我得到了我的代码的TypeError on line 22。完整的错误信息是：

TypeError: unsupported operand type(s) for |=: 'str' and 'bool' message when trying to run script 

我在下面包含了我的代码和 json 格式的示例 .txt 文件。

示例 JSON 格式文件

        {
            "positives": 1,

Answer 1

您将vt_result 转换为字符串：

vt_result = str(vt_result)

在内循环的第一次迭代中这不是问题，但在第二次迭代中，值没有重置，您尝试在字符串上执行|=（“True”或“False”）和一个布尔值，它失败了。

你可以通过移动来解决这个问题

vt_result = False

下面

for filename in os.listdir(path):

如果这不可行，因为您需要继续使用以前迭代的值，只需删除转换行：print 打印一个布尔值就好了。

Answer 2

错误表明在给定的行上，|= 运算符两侧的值与该操作的类型不兼容；一个是str，另一个是bool。 |= 之后的表达式应始终计算为bool，因此您需要找到vt_result 变成str 的位置。而且你明确地让它更远一点：

vt_result = str(vt_result)

所以下次通过 for 循环之后，当您再次运行 vt_result |= ... 行时，您会收到错误。
