lookuperror in python: a comprehensive guide (including tamil explanation & examples)

lookuperror is a base exception class in python that serves as the parent class for exceptions raised when a key or index is not found in a container (like lists, dictionaries, tuples). it's a crucial exception to understand for robust error handling in your python programs.

*understanding lookuperror*

think of `lookuperror` as a general warning sign that "something you're trying to find inside a data structure isn't there." instead of crashing your program outright, python throws this exception, giving you a chance to gracefully handle the situation and provide informative feedback to the user or take corrective action.

*key child exceptions of lookuperror*

`lookuperror` itself is rarely directly raised. instead, its child exceptions are more commonly encountered:

1. *indexerror:* raised when you try to access an index in a sequence (like a list, string, or tuple) that is out of bounds. for example, if a list has 5 elements (indices 0 to 4), trying to access `list[5]` will raise an `indexerror`.

2. *keyerror:* raised when you try to access a key in a dictionary that doesn't exist.

*why use lookuperror handling?*

*prevent program crashes:* instead of your program abruptly terminating, you can catch the `lookuperror` and handle it gracefully.
*informative error messages:* you can provide custom error messages to the user, making your program more user-friendly.
*robust code:* by handling potential `lookuperror` exceptions, your code becomes more resilient to unexpected inputs or data conditions.
*debugging:* catching and logging `lookuperror` exceptions can help you identify and fix errors in your code more easily.

*explanation:*

we create a list `my_list` with 5 elements.
we try to access `my_list[5]`, but the valid ...
