To build please run:

pip install wgrib-python

For configuring wgrib2, CC and FC environment variables need to set prior to calling pip, e.g.

export CC=gcc-7
export FC=gfortran-7

To use try the following python code:

from wgrib import wgrib_main  # wgrib1
import shlex

output = wgrib_main(shlex.split('-text -verf'))
print(output)

• Full wgrib2 support
• Fancier wrappings for more flexibility
