There is a python package that can be used to calculate the SPEI (as well as other useful indices).

Hi @faridradmehr, this is the original issue, re-awakened thanks to your additions.
https://github.com/os-climate/hazard/blob/main/src/hazard/models/drought_index.py
Based on xclim implementation https://xclim.readthedocs.io/en/stable/
Last things to do:

add concurrency (multi-threading) for SPEI index calculation stage (I'll add a suggested approach)
complete tests and sanity checks of results
perform clean run
