validare=validator_client()
try:
     validare.validate_client(client1)
except:
     ValidatorException
     print (ValidatorException)

client()是一个具有 5 个属性的类，第一个属性是 id，它有一个 getter 和 setter，所以这个类没有问题，但为什么当我运行这个时没有打印任何错误？

有几件事：你不是在调用那个getter，而是在获取方法（除非它是一个属性，在这种情况下，为什么它被称为get）。 此外，正如 @Martijn Pieters 在注释中所说，您的 except 子句正在捕获所有异常，然后打印ValidatorException类的字符串表示形式，而不是异常实例。

至于except条款，我认为您可能正在寻找的是：

except ValidatorException as ve:
    print(ve)
