Python Tutorial: Using Try/Except Blocks for Error Handling

Рет қаралды 681,234

8 жыл бұрын

We've all run into errors and exceptions while writing Python programs. In this video, we will learn how we can handle exceptions in specific ways and also look at the control flow of a try/except/else/finally statement. Understanding how to properly handle errors will provide us with the tools to make better software in the future. Let's get started.

@rezamostafid8810 2 жыл бұрын

Corey: very clear and useful introduction of all the main features and caveats....better than the Python book I'm current using to learn python. I'm not sure if you did this intentionally but you mention some points at the beginning ( and also later on ... ) that provide the motivation for exceptions to begin with. This in turn allows much better understanding of the 'else' and 'finally' clauses as well as the 'raise' Thanks for clearing the fog in my head!

Your videos are very helpful, Corey! tyvm Also, just to point out that it is better to close the file (f.close()) within the finally block, because it will be executed anyway, while the else block runs only if the try clause doesn't raise an exception.

@uzomaobasi3767 4 жыл бұрын

do you know why an exception is thrown when he mislabels the file name? and not the FileNotFoundError? It says ErrNo2 but shouldnt it be ErrNo1?
