Error Handling in Python Complete Tutorial | Everything to know about exception handling
In this video, we will be discussing error (exception) handling in Python. Exception handling is a way to handle errors that may occur in your code. Exception handling is very important to ensure that your code can run regardless of errors that occur. This prevents your program from crashing and ensuring high availability from a programming perspective.
When an error occurs, an exception is raised, and you can use try-except blocks to handle these exceptions and prevent your program from crashing. You can have multiple except blocks to handle different types of exceptions, or you can use a single except block without specifying an exception type to catch any exception that might be raised in the try block. You can also use the finally block to execute code that should run regardless of whether an exception is raised or not.
In Python, exceptions are errors that occur during the execution of a program. Exception handling allows you to handle these errors and gracefully exit your program or take an alternate action when an exception occurs.
To handle an exception in Python, you use the try and except statements. The code that you want to monitor for exceptions is placed in the try block, and the handling of the exception is placed in the except block.
You can also use the finally block to execute code, regardless of whether an exception occurred. This is useful for cleaning up resources, such as closing file handles or releasing database connections.
NOTE: About 6:30 into the video, I say let’s look at a case where this is an error, I meant a case where there is not an error.
