A handy way to work with Python is to use the Jupyter Notebook interface. This lets you make documents combining text, python code and images. You can run Jupyter at NCI using the CLEX Conda environment.
If you're making plots on a map check out the Cartopy library - this handles things like map projections, drawing coastlines and adding background images.
The xarray library is a great place to start if you're working with gridded NetCDF data. It allows you to easily open a file, perform common types of analyses like climatologies, and easily plot results.
Pandas is a similar library for tabular data, like you'd get from observations at a weather station.
Numpy and Scipy are the grandfathers of Python science. They provide optimised versions of standard mathematical functions, especially for working with arrays. Xarray and Pandas both use Numpy arrays to store data.
Bash is the most common language used in the Linux terminal, though there are alternatives like 'csh' and 'zsh'. There are a wide variety of command line programs available
