Python Recursive Function
RECURSIVE FUNCTION A function can call other functions. It is even possible for the function to call itself. These type of construct are termed as recursive functions. Factorial of a number is the product of all the integers from 1 to that number. For example, the factorial of 6 (denoted as 6!) is 1*2*3*4*5*6 = 720. # An example of a recursive function to # find the factorial of a number def calc_factorial(x): """This is a recursive function to find the factorial of an integer""" if x == 1: return 1 else: return (x * calc_factorial(x-1)) num = 4 print("The factorial of", num, "is", calc_factorial(num) EXPLANATION In the above example, calc_factorial() is a recursive functions as it calls itself. When we call this function with a positive integer, it will recursively call itself by decreasing the number. Each function ca...
