In general it contains a stack traceback listing source lines; however, it will not display lines read from standard input. Built-in Exceptions lists the built-in exceptions and their meanings. 8.3. Handling Exceptions ¶ It is possible to write programs that handle selected exceptions .
Exception handling is a fundamental skill for any Python developer. By properly implementing exception handling in your code, you can create more robust, user-friendly applications that gracefully handle errors instead of crashing.
Python Exception Handling
We raise an exception using the raise keyword followed by an instance of the exception class that we want to trigger. We can choose from built-in exceptions or define our own custom exceptions by inheriting from Python's built-in Exception class.
Both unit testing and exception handling are the core parts of Python programming that make your code production-ready and error-proof. In this tutorial, we have learned about exceptions and errors in Python and how to handle them.
