Handling Exceptions Using Try and Catch

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 brackets { }.

try:
  # statements

Catch and Except Block

When an error occurs in a try block, the PowerShell scripts search for a catch block to handle that error. A catch block has a list of statements to handle the failure or to recover from the error that was caught in the try block.
