Multiple Exception Handling: Supports handling different types of exceptions with varying measures, enhancing program flexibility.自定义异常：可以根据具体需求创建自定义异常类，使异常处理更加精确和直观。Custom Exceptions: Allows creating custom exception classes based on specific needs, making exception handling...
If none of the statements in thetryblock generates an exception, theexceptblock is skipped. Catching Specific Exceptions in Python For eachtryblock, there can be zero or moreexceptblocks. Multipleexceptblocks allow us to handle each exception differently. The argument type of eachexceptblock indicat...
Example 2: Handling Multiple Exceptions Here, we're trying to access an element at an invalid index in a list, which raises an 'IndexError'. The 'correct' except block catches this error and prints a message. The 'ZeroDivisionError' block is not executed, demonstrating how you can handle ...
If you are writing the code to handle a single exception, you can have a variable follow the name of the exception in the except statement. If you are trapping multiple exceptions, you can have a variable follow the tuple of the exception. This variable will receive the value of the excep...
When a Python script raises an exception, it must either handle the exception immediately otherwise it terminates and quits. Handling an exception If you have somesuspiciouscode that may raise an exception, you can defend your program by placing the suspicious code in atry:block. After the try...
If you try to raise multiple exceptions, the program will finish after handling the first exception. The rest will never be raised. You can show this using code similar to the following: Python # catch_first_only.py exceptions = [ZeroDivisionError(), FileNotFoundError(), NameError()] num...
1. Handling Multiple Exceptions You can handle multiple exceptions by specifying them in the except block or using a generic except block to catch all exceptions. try:result=int("abc")exceptValueError:print("ValueError occurred")exceptExceptionase:print(f"An error occurred:{e}") ...
The try block contains the code that might raise an exception. If a ZeroDivisionError occurs, the except block is executed, and an error message is printed. Handling Multiple ExceptionsThis example demonstrates how to handle multiple exceptions using a single try-except block. ...
If there is any exception, then execute this block. ... else: If there is no exception then execute this block. #The except Clause with Multiple Exceptions try: You do your operations here; ... except(Exception1[, Exception2[,...ExceptionN]]]): If there is any exception from the ...
类似if-elif-else语句，try-except也可以多分支。此外，异常语句还可以与else和finally配合使用。如果try中没有异常，跳过except；如果没有，则执行except中的语句，跳过else。最后finally内的都会执行。Similar to if-elif-else statements, try-except can also be multiple branches. In addition, exception statements...
