Python sorted() Function Tutorial | Sort Lists & Strings with Examples for Beginners
Learn Python’s `sorted()` function in this beginner-friendly tutorial! The `sorted()` function creates a new sorted list from any iterable—like lists, tuples, or strings—without changing the original. We’ll sort numbers `[5, 2, 9, 1, 5, 6]` in descending order and sort words `["ad", "bingo", "cake"]` by length in reverse order using `key=len`. Perfect for Python beginners, coding newbies, or anyone wanting to master sorting in Python with practical examples!
🔍 *What You'll Learn:*
How `sorted()` works with iterables (lists, strings)
Sorting in ascending and descending order (`reverse=True`)
Using `key` for custom sorting (e.g., by length)
Why `sorted()` doesn’t modify the original data
💻 *Code Used in This Video:*
Sort numbers in descending order
numbers = [5, 2, 9, 1, 5, 6]
print(sorted(numbers, reverse=True)) # Output: [9, 6, 5, 5, 2, 1]
print(numbers) # Output: [5, 2, 9, 1, 5, 6] (original unchanged)
Sort strings by length in descending order
words = ["ad", "bingo", "cake"]
print(sorted(words, key=len, reverse=True)) # Output: ['bingo', 'cake', 'ad']
🌟 *Why Learn sorted()?*
Sorting is a core skill in coding—used in data analysis, algorithms, and interviews! We’ll show how `sorted()` keeps your original data safe, explain the `key=len` trick for custom sorting, and compare it to `.sort()` (which modifies lists directly). Master this, and you’ll handle lists, strings, and more like a pro—great for projects, coding challenges, or just organizing data efficiently!

sorted() - Returns a new sorted list from an iterable without modifying the original
Sort numbers in descending order
numbers = [5, 2, 9, 1, 5, 6]
print(sorted(numbers, reverse=True)) # Output: [9, 6, 5, 5, 2, 1]
print(numbers) # Output: [5, 2, 9, 1, 5, 6] (original unchanged)
Sort strings by length in descending order
words = ["ad", "bingo", "cake"]
print(sorted(words, key=len, reverse=True)) # Output: ['bingo', 'cake', 'ad']
'bingo' (5 letters), 'cake' (4 letters), 'ad' (2 letters)
