Write a function to calculate the factorial of a number. The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. For example, for input 5 , the output should be 120

Apr 8, 2025 · In Python, we can calculate the factorial of a number using various methods, such as loops, recursion, built-in functions, and other approaches. Example: Simple Python program to find the factorial of a number. Explanation: This code calculates the factorial of a number n (which is 6 in this case) using a for loop.

Jan 31, 2023 · In this article, we are going to calculate the factorial of a number using recursion. Examples: Output: 120. Input: 6. Output: 720. Implementation: If fact (5) is called, it will call fact (4), fact (3), fact (2) and fact (1). So it means keeps calling itself by …

Nov 13, 2024 · Given the number n (n >=0), find its factorial. Factorial of n is defined as 1 x 2 x … x n. For n = 0, factorial is 1. We are going to discuss iterative and recursive programs in this post. Examples: The idea is simple, we initialize result as 1. Then run a loop from 1 to n and multiply every number with n.

Mar 20, 2025 · This Python tutorial explains, how to print factorial of a number in Python, Python program to print factorial of a number using function, Python program to find factorial of a number using while loop, etc.

Oct 7, 2019 · In this blog post, we’ll explore how to write a Python program to find the factorial of a number. Additionally, we’ll provide a step-by-step explanation and include example code with outputs. Understanding Factorials

Nov 19, 2022 · Discuss the different methods to find the python program to find factorial of a number with algorithm and code.

Jan 6, 2022 · The easiest way is to use math.factorial (available in Python 2.6 and above): If you want/have to write it yourself, you can use an iterative approach: fact = 1. for num in range(2, n + 1): fact *= num. return fact. or a recursive approach: if n < 2: return 1. else: return n * factorial(n-1)

Jul 9, 2024 · With the help of sympy.factorial(), we can find the factorial of any number by using sympy.factorial() method. Syntax : sympy.factorial() Return : Return factorial of a number. Example #1 : In this example we can see that by using sympy.factorial(), we are able to find the factorial of number that i

Write a Python Program to find the factorial of a number. If number is negative print the message otherwise find the factorial of the number. What is Factorial of a Number? Factorial of a number is the product of all positive integers from 1 to that number. It is denoted by the symbol “!”.
