How to Fix Python's "List Index Out of Range" Error in For Loops

The List Index Out of Range error often occurs when working with lists and for loops. You see, in Python, when you attempt to access an element using an index that lies outside the valid index range of the list, you're essentially telling the program to fetch something that isn't there, resulting in this common error. It's the interpreter's way of signaling that there's a misalignment in your expectations of the list's size and the actual indices present.

There's one big difference between them though: try-except is for Python while try-catch is for Java.
