How to use a recursion function in Python?
A recursion function is a function that can call itself. For example, let’s say we want to calculate the factorial of a given number. One way to solve this problem is to use a loop. But, we can use a recursion function to calculate the factorial of the number more conveniently.
def calculate_factorial(n): if n == 1: return n else: return n * calculate_factorial(n - 1) n = 5 print(calculate_factorial(n))
The above program will print the following output:
120
Please note that using recursion is more convenient. When a program is complex, but it can be broken into smaller problems that can be solved using a repetitive approach, we can use recursion. But, a recursion function is not memory efficient. So, in the above program, we can use the recursion function to calculate the factorial of a small number. If the number is very big, it will be better to use an alternative iterative approach instead. Otherwise, the program will not be memory efficient.
