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 to handle exceptions. Py...
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: block, include anexcept:statement, followed by a block of code which handles the problem as elegantly as possible. Syntax: Here is simple syn...
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...
In Python programming, exception handling is a very important skill. It allows a program to not crash immediately when encountering an error, but instead execute some predefined operations to handle these errors, ensuring the robustness and reliability of the program. By using the exception handling ...
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 ...
Example 1: Basic Exception Handling In this example, we attempt to divide a number by zero, which raises a 'ZeroDivisionError'. The 'except' block catches this error and prints an appropriate message, preventing the program from crashing. ...
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-...
