Answer 1

The problem seems to be that you haven't actually installed the required modules.

Lines of Python code like

from mpl_toolkits.basemap import Basemap

Are import statements that tell your script to use modules (or other bits of Python code) that you need to have already installed.

For each of the packages mentioned (NumPy, Matplotlib, Basemap) you will have to figure out how to install them on your system. In the case of NumPy and Matplotlib this can be complicated because they require compilation. For instance these are theNumpy instructions.

If you just wanted to try playing with the instructions in that blog post then you could use a service like PythonAnywhere which has numpy, matplotlib, and basemap installed already. (disclaimer, I work on PythonAnywhere...)
