Learning to extract information from ABAQUS files using Python scripts

Hello folks,

This is something that must have been asked several times. I want to
post process data obtained after running a FEM in ABAQUS. The
requested results are usually printed to the .dat file, .rpt file,
.odb file, etc. I would like to learn how to extract the information
that I need (i.e. displacements and stresses at the nodes) from this
file using Python scripting. The fact is that I am kind of new at
ABAQUS and have very little knowledge about Python. Therefore, any
help with websites, examples, tutorials, etc. would be appreciated.

Thank you!

Andres
