PowerShell is a go-to scripting language for almost ANYTHING! Now, if you’re hoping to learn Python, then you’re in the right place. As you start this course, you’ll begin to notice that there are a lot of patterns and concepts shared between the two languages. 

Thus during this course, you will easily be able to relate new Python concepts to the concepts you already know in PowerShell, a learning style called Associative Learning. 

This PowerShell Scripting guide to Python is designed to make you familiar with syntax, semantics, and core concepts of the Python language. And by using concepts you already know in PowerShell, you’ll be able to learn Python fast and effectively in a way that sticks with you for a longer period of time.

Learning Python through PowerShell Concepts

A `finally` block contains a set of statements that are finally executed no matter how the program ended. This is generally used to free any resources that were used in the `try..catch` blocks of our program.
Basically, the `finally` block contains the piece of program that is executed after the completion of both the `Try` and `Catch` blocks, regardless of whether an error occurred. The primary purpose of this block is to clean resources, like removing or disposing of objects used by the program from memory to make the memory free.

# Powershell

PowerShell syntax:

Let's understand the syntax of the `finally` block in Powershell.

```PowerShell
try{
  # statements to be monitored for errors
}
catch{
  # handle errors here
}
finally{
  # final tasks: these are executed no matter if an error is thrown or not
}
```

Let's take an example in PowerShell which we have discussed in the previous lesson. We will add a `finally` block to that example and will see that the `finally` block will always be executed. 

Let's learn about the `finally` block and how to use it for handling exceptions.
