Handling Exceptions Using Try and Catch
Explore exception handling in Python and PowerShell by learning how try blocks detect errors, catch or except blocks handle specific exceptions, and finally blocks execute essential cleanup code. Understand syntax differences and how to define multiple error handlers to manage failures gracefully.
We'll cover the following...
The way exception handling works is relatively consistent across programming languages. First, we attempt to execute a section of the program in a try block. If it throws an error, we can handle it in a catch block and, at last, perform some final mandatory steps in the finally block. Let us look into each of these blocks in detail one at a time.
Try Block
The 'try' block defines a section of code that we want the programming language to monitor for any errors or exceptions. The following is the PowerShell syntax for the try block:
try{
# statements
}
Python syntax is similar except for a colon (:) after the try keyword and an indentation instead of curly ...
