Uhh, putting this in perspective... until a spammer revived the thread just now, it was asked, answered, and finished with, all back in 2016. I don't think anyone's still waiting on answers here.

Re: >>> %matplotlib inline results in SyntaxError: invalid syntax
"%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.

Thanks. That's what I have been doing and have never used py.exe. For context Esri distributes ArcPy as a scripting language using 3.9. By default the base install can't be modified so if you want additional libraries or a tool like Spyder it has to be in a virtual. -- https://mail.python.org/mailman/listinfo/python-list
