To find the factorial of a given number by defining a function
A factorial is the product of all the integers from 1 to that number.
n!=n*(n-1)…..*1
In this code, we use the concept of a recursive function, that is, the functions are called multiple times while executing it once.

def factorial(n):
if n <= 0:
return(1)
else:
val=n*factorial(n-1)#Since n!=n*(n-1)!
return(val)
m=input("Enter a number")#taking input from user
num=int(m)#By default, the input is considered to be a string. so we convert it into an integer
print(factorial(num))
