I’ve been immersed in the world of Python programming for approximately three years. During this time, I’ve come to appreciate the elegance and power of this versatile language. In this post, designed for both fun and education, I’ll be presenting a collection of one-liner Python code snippets. Whether you’re a seasoned developer or a beginner, these concise lines of code offer insights into the simplicity and effectiveness of Python, demonstrating how a single line can accomplish what might take several lines in other languages.

  1. Reverse a String:
reversed_string = "Hello World"[::-1]
  1. Check if a Number is Even:
is_even = lambda x: x % 2 == 0
  1. Find the Intersection of Two Lists:
intersection = list(set(list1) & set(list2))
  1. Remove Duplicates from a List:
no_duplicates = list(set(my_list))```
  1. Calculate the Length of a String without Using len():
length = sum(1 for _ in 'Hello World')
  1. Check if a List Contains All Elements of Another List:
contains_all = all(elem in list1 for elem in list2)
  1. Generate a String of Random Characters:
import random; 
random_str = ''.join(random.choices('abcdefghijklmnopqrstuvwxyz', k=10))
  1. Convert a List of Integers to a Single Number:
num = int(''.join(map(str, [1, 2, 3, 4, 5])))
  1. Palindromic Check:
is_palindrome = lambda s: s == s[::-1]
  1. List Flattening:
flatten_list = sum([[1, 2], [3, 4]], [])
  1. Find the Most Frequent Element in a List:
most_frequent = max(set(my_list), key=my_list.count)
  1. Merge Two Dictionaries:
merged_dict = {**dict1, **dict2}

Finally, I hope you enjoyed reading this and had the opportunity to learn something new. If you have any feedback, please feel free to leave a comment below. If you prefer not to comment publicly, you can always send me an email. Also I would love to see your favorite python one liner code snippets.

If you’re interested in advancing your programming skills and would love to learn how to build cool projects like Docker, BitTorrent, or even understand the internals of your favorite tools such as Git, grep and etc by recreating them in your preferred programming language, I highly recommend you join Code Crafters.
