Top 10 Python One Liners! 1️⃣ Reverse a string:

reversed_string = "Hello World"[::-1]

2️⃣ Check if a number is even:

is_even = lambda x: x % 2 == 0

3️⃣ Find the factorial of a number:

factorial = lambda x: 1 if x == 0 else x * factorial(x - 1)

4️⃣ Read a file and print its contents:

[print(line.strip()) for line in open('file.txt')]

5️⃣ Create a list of squares:

squares = [x**2 for x in range(10)]

6️⃣ Flatten a list of lists:

flat_list = [item for sublist in [[1, 2], [3, 4], [5, 6]] for item in sublist]

7️⃣ Find the length of a list:

length = len([1, 2, 3, 4])

8️⃣ Create a dictionary from two lists:

keys = ['a', 'b', 'c']; values = [1, 2, 3]; dictionary = dict(zip(keys, values))

9️⃣ Generate a list of random numbers:

import random; random_numbers = [random.randint(0, 100) for _ in range(10)]

🔟 Check if a string is a palindrome:

is_palindrome = lambda s: s == s[::-1]

Mastering these one-liners can significantly improve your coding efficiency and make your code more concise. https://t.me/pythonRe ✉️
