Recursion : “The repeated application of a recursive procedure or definition.” – Oxford Languages
In programming we have recursion functions, these functions are the functions which call themselves in the same function.
In simple words if any function calls itself then it is known as recursion.

"""Function to return the factorial
of a number using recursion"""
if n == 1:
num = int(input("Enter a number: "))
# check is the number is negative
if num < 0:
print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
print("The factorial of 0 is 1")
print("The factorial of",num,"is",recur_facto(num))
