Am I missing something? The __init__.py file indicates that the files in a folder are part of a Python package. Without an __init__.py file, you cannot import files from another directory in a Python project. How to Use the Python __init__.py FileWhile taking a look at sample Python projects, you may have seen this file, __init__.py. You may have wondered what it was, why it’s there if it’s empty, and how it works. This post will answer all of those questions! Find Your Bootcamp Match

Here is an example file structure that includes __init__.py: main_package/ __init__.py file1.py file2.py file3.py main.py The main folder is our Python directory that we want to treat as if it were a Python package. To be treated as such, we have to include an __init__.py file that relays this information to the Python interpreter. The rest of the files are just Python files that each have different information in it that we might want to use elsewhere. This could be a Class, a function, etc. The main.py is where we are going to call for the functions that we have stored in main_package. You’ll see how this works in a minute, but first let’s take a look at the __init__.py file. What is __init__.py?The __init__.py file lets the Python interpreter know that a directory contains code for a Python module. An __init__.py file can be blank. Without one, you cannot import modules from another folder into your project. The role of the __init__.py file is similar to the __init__ function in a Python class. The file essentially the constructor of your package or directory without it being called such. It sets up how packages or functions will be imported into your other files. In its simplest case, the __init__.py file is an empty file. However, it is also used to set up imports, so they can be accessed elsewhere. There are three main ways to do that: 1. |
