Intermediate Python Tutorial: How to Use the init.py File

Показать описание

A succinct tutorial on how to use the __init__.py file to import directories as python libraries.

Welcome to my series for Learning Python, where I will be teaching fundamental concepts in the Python programming language.

These videos will focus on one aspect of Python at a time, but your understanding of the material will be greatly improved through usage. I recommend applying the concepts described here in your own project, or viewing the Developer Diary series where I use these tools on bigger projects.

Hello everyone! Another user was having a problem that I want to share with you guys. When you import a package to python, the interpreter searches several paths to find your library - one of which being the working directory. If, however, one of those other paths has a library with the same name, that one will take precedence! If you create a library called Matplotlib, python will still import the original instead of yours!

I came here to learn __init__, but the way you have demonstrated is absolutely amazing; now I understand what from, import, and __init__.py do. Brilliant!.

Jeeez I always used init files without typing in anything. 2 years passed here I am finding out this blessing of information. This will clean up a lot of mess in my projects. Huge

Thanks for that clear description. This make reusing code so much easier. I have been trying to figure this out for two weeks.

Thanks, Eric. This short video was just what I was looking for. I'm a Python newcomer and packages have been difficult to grok until now.

Very good explanation. I was wondering why a lot of projects had hundreds of lines of code added to their __init__ file and this has helped a lot. Thanks mate!

Thank you! The first two minutes explained my confusion about why some of my code would work without errors when other code wouldn't. Definitely helped me. Thanks!!!
