Working with Strings in Python

Introduction
Quick recap
Indexing and slicing
15. Index out of range
Summary

Instruction

Good job! Let's do one final experiment with string indices. What happens when you try to access a non-existent element?

Exercise

Take a look at the template code. Try to access an element that is not present in the string.

For instance, try first_letters[7] or first_letters[-9].

In both cases, we get an IndexError: string index out of range. That's not a problem when we're testing things, but when your users encounter this, their programs will stop working (crash)!
