NumPy tutorials

For the rendered tutorials, see https://numpy.org/numpy-tutorials/.

The goal of this repository is to provide high-quality resources by the NumPy project, both for self-learning and for teaching classes with. If you're interested in adding your own content, check the Contributing section. This set of tutorials and educational materials is not a part of the NumPy source tree.

To download a local copy of the .ipynb files, you can either clone this repository or navigate to any of the documents listed below and download it individually.

Contributing

We very much welcome contributions! If you have an idea or proposal for a new tutorial, please open an issue with an outline.

Don’t worry if English is not your first language, or if you can only come up with a rough draft. Open source is a community effort. Do your best – we’ll help fix issues.

Images and real-life data make text more engaging and powerful, but be sure what you use is appropriately licensed and available. Here again, even a rough idea for artwork can be polished by others.

The NumPy tutorials are a curated collection of MyST-NB notebooks. These notebooks are used to produce static websites and can be opened as notebooks in Jupyter using Jupytext.

Note: You should use CommonMark markdown cells. Jupyter only renders CommonMark.

Why Jupyter Notebooks?

The choice of Jupyter Notebook in this repo instead of the usual format (reStructuredText, through Sphinx) used in the main NumPy documentation has two reasons:

• Jupyter notebooks are a common format for communicating scientific information.
• Jupyter notebooks can be launched in Binder, so that users can interact with tutorials
• rST may present a barrier for some people who might otherwise be very interested in contributing tutorial material.

Note

You may notice our content is in markdown format (.md files). We review and host notebooks in the MyST-NB format. We accept both Jupyter notebooks (.ipynb) and MyST-NB notebooks (.md). If you want to sync your .ipynb to your .md file follow the pairing tutorial.

Adding your own tutorials

If you have your own tutorial in the form of a Jupyter notebook (a .ipynb file) and you'd like to add it to the repository, follow the steps below.

Create an issue

Go to https://github.com/numpy/numpy-tutorials/issues and create a new issue with your proposal. Give as much detail as you can about what kind of content you would like to write (tutorial, how-to) and what you plan to cover. We will try to respond as quickly as possible with comments, if applicable.

Check out our suggested template

You can use our Tutorial Style Guide to make your content consistent with our existing tutorials.

Upload your content

Fork this repository (if you haven't before).

In your own fork, create a new branch for your content.

Add your notebook to the content/ directory.


Update the environment.yml file with the dependencies for your tutorial (only if you add new dependencies).

Update this README.md to include your new entry.


Update the attribution section (below) to credit the original tutorial author, if applicable.

Create a pull request. Make sure the "Allow edits and access to secrets by maintainers" option is selected so we can properly review your submission.


🎉 Wait for review!

Building the Sphinx site locally

Building the tutorials website, which is published at https://github.com/numpy/numpy-tutorials, locally isn't necessary before making a contribution, but may be helpful:

conda env create -f environment.yml
conda activate numpy-tutorials
cd site
make html

Translations

While we don't have the capacity to translate and maintain translated versions of these tutorials, you are free to use and translate them to other languages.
