#41 Python Tutorial for Beginners | Factorial using Recursion

In this lecture we will learn:
– Recursion in Python
– Find the factorial of a number by using the recursion
– How the function inside a function works?
– Logic for finding the factorial using recursion

#1
– Recursion is a function calling itself.
1. Create a variable to store the factorial of a number.
2. Assign the variable by the fact() function and pass a number in it as an argument.
3. Print the value of the variable to get the result.
4. Define the function say fact() above the main code.
– A function can be defined by using the keyword def.
def fact(n):
5. Call the same function inside the fact() function by applying the correct logic and return its value.
return n*fact(n-1)
6. Apply the condition for the factorial of a 0 as it is always 1.
– In this way, the factorial of a number will be printed by using the recursion.
