sum of numbers recursion python

Показать описание
Recursion is a programming technique where a function calls itself in order to solve a problem. In this tutorial, we will explore how to calculate the sum of a sequence of numbers using recursion in Python. This is a common example to illustrate the concept of recursion and can be a helpful way to understand how recursive functions work.
Before you begin, make sure you have Python installed on your computer. You can download and install Python from the official Python website.
Recursion consists of two parts: the base case and the recursive case.
Base case: This is the condition under which the recursive function stops calling itself. Without a base case, the recursion would continue indefinitely, resulting in a stack overflow.
Recursive case: This is the part of the function that calls itself, making the problem smaller with each recursive call until it reaches the base case.
In this tutorial, we will create a Python function that calculates the sum of numbers from 1 to n using recursion.
Here's the Python code for this function:
Now, let's break down how this function works:
To use the sum_numbers_recursive function, simply call it with the desired value of n. Here's an example:
When you run this code, it will output:
The sum_numbers_recursive function recursively calculates the sum of numbers from 1 to 5, which is 15 in this case.
In this tutorial, we've learned how to calculate the sum of numbers using recursion in Python. Understanding the concept of recursion and how to create recursive functions is a fundamental skill in computer programming. You can use this knowledge to solve a wide range of problems in a more elegant and efficient way.
