PYHDF4 is a python wrapper around the NCSA HDF version 4 library, which implements the SD (Scientific Dataset), VS (Vdata) and V (Vgroup) API’s. NetCDF files can also be read and modified. It is a successor of Python-HDF4 which is a fork of pyhdf.

Fire is a library for automatically generating command line interfaces from absolutely any Python object. The following are the advantages:

• A simple way to create a CLI in Python.

• A helpful tool for developing and debugging Python code.

• Helps with exploring existing code or turning other people's code into a command line interface.

• Makes transitioning between Bash and Python easier.

• Makes using a Python REPL easier by setting up the REPL with the modules and variables you'll need already imported and created.
