Python List Checking and Verification Programs (original) (raw)

Last Updated : 06 Feb, 2025

Lists in Python are versatile, but often, we need to verify their contents, structure, or relationships with other lists. Whether we're checking for duplicates, order, existence of elements or special conditions, Python provides efficient ways to perform these checks.

This article covers various list verification techniques, including:

• Checking if a list is empty, sorted or contains unique elements.
• Verifying element presence, conditions and comparisons between lists.
• Detecting subsets, consecutive elements and specific patterns.

Here's the list of programs:

• Check if element exists in list in Python
