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.

# Error Handling

Handling errors or exceptional conditions is a key part of any programming language. Even small scripts and programs should ideally be  written with the ability to catch exceptions and handle them gracefully in an expected manner. In this chapter, we are going to delve deeper into types of errors and how to handle  them. We will learn to throw, catch, and create custom errors.

## Types of Errors

Generally, there are 3 types of errors: **syntax**, **runtime**, and **logical** errors. Let’s look into each of these errors one at a time.



## Syntax errors

In any language , the arrangement of words and phrases to create well-formed sentences is called syntax. In Computer Science, however, syntax is a structure of statements. Two important takeaway words from these definitions are "well-formed" and "structure".

So, in any programming language, a syntax error is usually observed when the parser detects an incorrect statement or finds a programming construct like a parenthesis or bracket missing in the program. In other words, a syntax error is a grammatical error for a programming language that expects developers to provide statements in a specific structure. If this specific structure is not observed, an error will be thrown. The following are some common examples of syntax errors:


* Misspelled cmdlets, variables, or names of a function.
* Missing semicolons or improper indentation.
* Improperly matched parentheses `( )`, square brackets `[ ]`, or curly braces `{ }`.

Let's see some examples to understand this better.

### PowerShell
```
dir()
write-hst
```
Type these commands one by one in the terminal below to see the errors.
