4,809 PointsFirst of all, it's always a good idea to include your code in your question.
Catching and raising exceptions are used when you know something might crash your program. If you have a function that can take invalid input (like the input function), you surround that code with the try function. Then, you use the catch function to prevent the exceptions you think might happen. If there were no exceptions, you use the else keyword to continue reading your code.
The raise function is used when you can catch an exception manually. Instead of using the try, you use other methods like if statements. You then use the keyword "raise" to catch that error in your error handling code. That code might reset some variables and ask the user for input again, so instead of re-writing all of that code you write it in your catch and use it as your exception protocol for the rest of the script.

# Code exampleAnd basically you need to do 2 things in this challenge. Determine whether or not a string is less than 3 characters long, and if it is throw an exception.
You can get the length of a string using the len() function. So your code should look something like this:

But if you want we can definitely handle this by e-mail instead of clogging up this thread.
