Python Program to Find Factorial of Number Using Recursion: In this program, you’ll learn to find the factorial of a number using recursive function.
Factorial: Factorial of a number specifies a product of all integers from 1 to that number. It is defined by the symbol explanation mark (!).
For example: The factorial of 5 is denoted as 5! = 12345 = 120.

# Factorial of a number using recursion
def recur_factorial(n):
if n == 1:
return n
else:
return n*recur_factorial(n-1)
num = 7
# check if 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")
else:
print("The factorial of", num, "is", recur_factorial(num))
