You now know everything you need to know to solve the following problem: Task: Write a Python one-liner solution that computes the number of permutations n! of a set with n elements. ## One-Liner Factorial Function: factorial = lambda n: n * factorial(n-1) if n > 1 else 1. ## Factorial of 5. WebMay 12, 2024 · Python Recursion occurs when a function call causes that same function to be called again before the original function call terminates. For example, consider the well-known mathematical expression x! (i.e. the factorial operation). The factorial operation is defined for all nonnegative integers as follows: If the number is 0, then the answer is 1.
