Python提供了大量的内置异常类型,如`ZeroDivisionError`, `TypeError`, `ValueError`, `FileNotFoundError`, `KeyboardInterrupt`等。你可以根据需要捕获特定类型的异常。 ## 3. try-except-finally - `try`:包含可能会抛出异常的代码。 - `except`:捕获异常。可以指定要捕获的特定类型,不指定则捕获所有异常。 - ...
1. 定义异常类:首先,我们需要定义一个异常类,用于表示特定的错误或异常情况。例如,我们可以定义一个名为`ValueError`的异常类,用于表示数值错误。 ```python class ValueError(Exception): def __init__(self, message="ValueError: The provided value is invalid."): self.message = message super().__init_...

c = ((a+b) / (a-b))exceptZeroDivisionError:print("a/b result in 0")else:print(c) Finally Python提供了一个关键字finally,它总是在try和except块之后执行。finally块总是在try块正常终止后或try块由于某些异常终止后执行。 try:# Some Code...except:# optional block# Handling of exception (if ...
Python Exception Handling Python中的错误可以有两种类型,即error和exception。error是程序中的问题,程序会因此停止执行。另一方面,当某些内部事件发生时,会引发异常,从而改变程序的正常流程。 error 顾名思义,代码中引发的错误。例如语法错误,导致程序终止。
Python Exception Handling In the last tutorial, we learned aboutPython exceptions. We know that exceptions abnormally terminate the execution of a program. Since exceptions abnormally terminate the execution of a program, it is important to handle exceptions. In Python, we use thetry...exceptblock...
Nested Exception Handling in Python We need nested exception handling when we are preparing the program to handle multiple exceptions in a sequence. For example, we can add another try-except block under the `else` statement. So, if the first statement does not raise an exception and check th...
Exception handling When using the Python SDK, you should be prepared to handle the following exceptions: Any response received by the SDK with a non-2xx HTTP status will be thrown as aServiceError AValueErrorwill be thrown if you provide invalid parameters to a method call or when setting ...
