python 执行时报错AttributeError: 'dict' object has no attribute 'has_key'

问题：

python 执行时报错

sortedResult = self.sortResult(result.result)
File "D:\Python39\lib\HTMLTestRunner.py", line 642, in sortResult
if not rmap.has_key(cls):
AttributeError: 'dict' object has no attribute 'has_key'
[Finished in 0.2s with exit code 1]

解决方案：

查阅资料发现，Python3以后删除了has_key()方法

打开HTMLTestRunner.py该文件第642行，将 if not rmap.has_key(cls):改为 if not cls in rmap: 保存

再次运行脚本时，成功。
