 Alternatively, you can format your code using:

-We also require Python code to use newer syntax of Python. You can upgrade automatically by running:
-
-.. code-block:: shell
-
-    $ make pyupgrade
-
-Additionally, we use a linter to verify that imports are correct. You can run it with:
-
-.. code-block:: shell
-
-    $ make flake8
-
-In the rare case when you cannot fix a flake8 error, use ``# noqa`` to make the linter
-ignore that error. Note that in most cases, it is better to fix the issues than ignoring them.
