Powerful One-Liners in Python You Should Know!


1. Swap Two Numbers

n1, n2 = n2, n1


2. Reverse a String

reversed_string = input_string[::-1]


3. Factorial of a Number

fact = lambda n: [1, 0][n > 1] or fact(n - 1) * n


4. Find Prime Numbers (2 to 10)

primes = list(filter(lambda x: all(x % y != 0 for y in range(2, x)), range(2, 10)))


5. Check if a String is Palindrome

palindrome = input_string == input_string[::-1]
