Exporting web plot to python code in order to reformat - help!

I’m trying to export a plot made through the web-based tools into python code in order to fine tune the formatting settings of the plot. After exporting the code into a file, and then attempting to run the code via python 3.6 is giving me a bunch of authentication errors, even though I have confirmed I can publish novel plots within the python environment.

Any ideas? I’m getting the following errors (running this on OS X: python3 installed via homebrew on my machine). Is this the best way to do what I’m trying to do? Thanks!!!
