factorial() in PythonNot many people know, but python offers a directfunction that can compute the factorial of a numberwithout writing the whole code for computingfactorial. This method is defined in“math” module of python. Because it has Ctype internal implementation, it isfast.

Python Program to Find the Factorial of aNumber Factorial is a non-negative integer. Itis the product of all positive integers less than or equalto that number for which you ask forfactorial.
Beside above, what is Fibonacci series in Python? Python Program to Display FibonacciSequence Using Recursion A Fibonacci sequence is a sequence of integerswhich first two terms are 0 and 1 and all other terms of thesequence are obtained by adding their preceding two numbers.For example: 0, 1, 1, 2, 3, 5, 8, 13 and so on See this example:def recur_fibo(n):
