Using a tuple of exception types is a simple and concise way to catch multiple exceptions in a singleexceptblock in Python. When an exception occurs in thetryblock, Python checks if the exception is an instance of any of the exception types listed in the tuple. If so, the correspondingexce...
# Executes if no exceptions4、AS关键字 在捕获异常时,可以使用as关键字将异常分配给一个变量,这样可以显示详细信息并使调试更容易。 try: # Some operation except Exception as e: print(f"Error: {e}")5、捕获多个异常 元组可用于在一行中捕获多种异常类型,从而简化错误处理代码。 try: # Risky operation...
This time, if you catch either a ValueError or ZeroDivisionError exception, you handle it with the same except clause. You also could’ve included additional except clauses for other exceptions if you wanted to. These would’ve worked for you in the same way as before. You can then test ...
The main way to handle exceptions in Python is by using the try and except statements. The basic syntax is as follows:还可以添加更多的异常处理分支，甚至一个通用的 except 来捕获所有未指定类型的异常。 You can also add more exception-handling branches or even a generic except to catch all ...
