Python sorted() Function Explained with Examples: Custom Master Sorting with Key & Reverse Parameter
🧠 *Python sorted() Function: Master Custom Sorting with key & reverse | NeuralAICodeCraft*
Master the `sorted()` function - Python's most versatile sorting tool! Learn how to sort any iterable with custom rules.
📌 *What you'll learn:*
*sorted() BASICS*
▸ Syntax: `sorted(iterable, key=None, reverse=False)`
▸ Returns NEW sorted list (original unchanged)
▸ Works with ANY iterable (lists, tuples, dicts, strings)
*sorted() vs list.sort()*
▸ sorted() creates new list - original intact
▸ sort() modifies in-place - original changed
▸ When to use each
*THE reverse PARAMETER*
▸ `reverse=False` (default) - Ascending order
▸ `reverse=True` - Descending order
▸ Examples with numbers and strings
*THE key PARAMETER*
▸ Custom sorting with key functions
▸ Sorting by length: `key=len`
▸ Sorting by last character: `key=lambda x: x[-1]`
▸ Sorting by custom criteria
*ADVANCED TECHNIQUES*
▸ Sorting dictionaries (by keys, by values)
▸ Sorting lists of tuples (by any element)
▸ Sorting custom objects (by attributes)
▸ Multiple criteria sorting
▸ Case-insensitive sorting
