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
instead of calling the square root function with a negative number, we could have checked the value first and then raised our own exception. The code fragment below shows the result of creating a newRuntimeErrorexception. Note that the program would still terminate but now...
If the assertion fails, Python uses ArgumentExpression as the argument for the AssertionError. AssertionError exceptions can be caught and handled like any other exception, using the try-except statement. If they are not handled, they will terminate the program and produce a traceback. Example He...

Thetrykeyword in Python initiates exception handling blocks to gracefully manage runtime errors. Paired withexcept,else, andfinally, it prevents program crashes by capturing and processing exceptions. This tutorial covers error handling techniques with practical examples. ...
Run the program and enter positive integer. Expected Output: 1 2 Enter your age: 12 age is even Again run the program and enter a negative number. Expected Output: 1 2 Enter your age: -12 Only integers are allowed Using Exception objects ...
When Python encounters an error, it raises an exception, which can stop the program from running unless the exception is handled. Exception handling allows us to manage errors gracefully, ensuring that our program can continue running or exit cleanly. This tutorial will focus on examples to help...
在英语口语交流中,你可能会说 “Proper error and exception handling are crucial for the robustness and reliability of the program.”(正确处理错误和异常对于提高程序的健壮性和可靠性至关重要)。 不同于 C/C++,Python 提供了一套完善的错误和异常处理机制。在接下来的章节中,我们将详细介绍 Python 的错误和...

When an exception occurs, Python creates an exception object and stops the program unless the exception is handled. Common exceptions include ZeroDivisionError, TypeError, and FileNotFoundError. Handling Division by ZeroThis example demonstrates how to handle a division by zero error using a try-...
