Pythonic Wonders: 100 One-Liners for Efficient Coding Mastery

Welcome to the realm of Pythonic efficiency! In this collection, we present “Pythonic Wonders: 100 One-Liners for Efficient Coding Mastery.” Python, known for its readability and conciseness, allows developers to achieve remarkable feats in just a single line of code. Whether you’re a seasoned coder looking for elegant solutions or a newcomer eager to explore the power of Python, these one-liners cover a diverse range of tasks — from basic operations to more complex algorithms. Join us on a journey through the art of concise coding, where each line speaks volumes in the language of Python.

1. Print “Hello, World!”: print("Hello, World!")
2. Swap two variables: a, b = b, a
3. Check if a number is even: is_even = lambda x: x % 2 == 0
4. Find the square of a number: square = lambda x: x**2
5. Reverse a string: reversed_str = lambda s: s[::-1]
6. List comprehension to get even numbers from a list: evens = [x for x in range(10) if x % 2 == 0]
7. Calculate the sum of a list: list_sum = sum([1, 2, 3, 4, 5])
8. Check if a string is a palindrome: is_palindrome = lambda s: s == s[::-1]
9. Generate a list of squares: squares = [x**2 for x in range(5)]
