The open-source Python package pyam provides a suite of tools and functions for analyzing and visualizing input data (i.e., assumptions/parametrization) and results (model output) of integrated-assessment models, macro-energy scenarios, energy systems analysis, and sectoral studies.
The comprehensive documentation is hosted on Read the Docs!
The pyam package was initially developed to work with the IAMC template, a timeseries format for yearly data developed and used by the Integrated Assessment Modeling Consortium (IAMC).

The package also supports timeseries data with a sub-annual time resolution:
Read the docs for more information about the pyam data model or look at the data-table tutorial to see how to cast from a variety of timeseries formats to a pyam.IamDataFrame.
