Store the Result of a Function in a List in Python: A Step-by-Step Guide

Introduction

Have you ever faced the challenge of storing outputs from a function into a list in Python? This is a common scenario when dealing with functions that return strings, particularly when processing data like key presses from a remote control. In this guide, we will walk through the process of capturing multiple outputs from a function and storing them in a list for easy access and manipulation later on.

The Problem

Imagine you have a function that listens for key presses using a daemon socket. While this function performs its job effectively, it currently returns separate string objects one at a time rather than a collection of results. Here’s a quick look at the function and its output:

Observed Output

When the function is called, you may see output similar to this:

The issue is clear: the function returns individual string outputs instead of a list that could host multiple entries. In order to efficiently collect all these keys, we need to modify our approach.

The Solution: Storing Outputs in a List

To store multiple string objects returned by the function in a list, we can follow these steps:

Initialize an Empty List: Create an empty list before calling the function.

Append Outputs to the List: Each time the function is called, append its output to the list.

Let's break it down into code:

This code ensures that every time getKey() is called, its returned values are collected and stored in the keys list. The final output will look something like this:

Conclusion

Storing results from functions into lists is straightforward once you understand the process. By initializing an empty list and using the append() method, you can efficiently gather multiple outputs for later use. This approach not only simplifies data handling but also enhances your ability to work with dynamic input streams, such as key presses from an IR remote.

Now that you've learned how to capture and store function outputs in Python, you can apply this technique to various applications in your coding projects! If you have any questions or need further clarification, feel free to leave a comment below. Happy coding!
