"%matplotlib inline" is a magic command that changes how plots render when
working with IPython. Read more here: https://stackoverflow.com/a/43028034
The article you linked assumes you are working in an IPython shell, not
IDLE. This is common in the data science world.
You may already have IPython installed. Try running it from a command line
with `python -m IPython`. If that doesn't work, you can first install it
with `python -m pip install IPython`, then run the 1st command.
IPython is commonly used as a Jupyter Notebook kernel. See
https://jupyter-notebook-beginner-guide.readthedocs.io/en/latest/index.html
for more information about Jupyter Notebook.
I'd also recommend a newer version of python. Python 3.4 reached end of
life almost 5 years ago. Some of the packages used in the linked article no
longer officially support python 3.4. That doesn't necessarily mean that
you'll experienced issues using python 3.4, but much has changed in the 7
years since that article was written.
