Before installing any dependencies or writing code, it's a great idea to create a

virtual environment. LINCC-Frameworks engineers primarily use `conda` to manage virtual

environments. If you have conda installed locally, you can run the following to

create and activate a new environment.

# Introducing Jupyter Notebooks in Sphinx

This notebook showcases very basic functionality of rendering your jupyter notebooks as tutorials inside your sphinx documentation.

As part of the LINCC Frameworks python project template, your notebooks will be executed AND rendered at document build time.

You can read more about Sphinx, ReadTheDocs, and building notebooks in [LINCC's documentation](https://lincc-ppt.readthedocs.io/en/latest/practices/sphinx.html)

``` python

def sierpinsky(order):

    """Define a method that will create a Sierpinsky triangle of given order,

    and will print it out."""

    triangles = ["*"]

    for i in range(order):

        spaces = " " * (2**i)

        triangles = [spaces + triangle + spaces for triangle in triangles] + [

            triangle + " " + triangle for triangle in triangles

        ]

    print(f"Printing order {order} triangle")

    print("\n".join(triangles))

```

Then, call our method a few times. This will happen on the fly during notebook rendering.
