cdflib is a python module to read/write CDF (Common Data Format .cdf) files without needing to install the CDF NASA library.

Python ≥ 3.6 is required. This module uses only Numpy, no complicated prereqs.

To install, open up your terminal/command prompt, and type:

pip install cdflib

There are two different CDF classes: a cdf reader, and a cdf writer.

Currently, you cannot simultaneously read and write to the same file. Future implementations, however, will unify these two classes.
