     def __init__(self,erori):
         self.__erori=erori
     def get_erori(self):

client1=client("",2,3,4,5)
validare=validator_client()
try:
     validare.validate_client(client1)
except:
     ValidatorException
     print (ValidatorException)

client()是一个具有5个属性的类，其中第一个属性是id，它具有一个getter和setter，所以该类没有问题，但是为什么在我运行此命令时不打印任何错误？

Answer 1

几件事：您不是在调用该getter，而是在获取该方法（除非它是一个属性，在这种情况下，为什么将其称为get）。 另外，正如@Martijn Pieters在评论中所说，您的except子句将捕获所有异常，然后打印ValidatorException类的字符串表示形式，而不是异常实例。

至于except子句，我想您可能正在寻找的是：

except ValidatorException as ve:
    print(ve)
