.. _python_packages: Python Packages =============== `grrproc `_. This python package allows the user to compute recursive r-process abundance relations (the GrRproc relations) and apply them to solutions of r-process networks. `lvlspy `_. This python package allows the user to store, retrieve, and compute data about quantum level systems. The input and output interact with `liblvls `_ codes. `wneq `_. This python package allows the user to compute nuclear equilibria relevant for nucleosynthesis. `wnnet `_. This python package allows the user to handle webnucleo reaction networks. `wnpoly `_. This python package allows the user to compute polynomials useful for webnucleo codes. `wnstatmech `_. This python package allows the user to compute the statistical mechanics of fermions and bosons. `wnutils `_. This python package allows the user to read, graph, and animate `libnucnet `_ input and output from Webnucleo codes. `xmlcoll `_. This python package allows the user to work with data about collections of items and to read those data from and write them to XML.
