rki-covid19csv-parser 1.2.0

A simple module to work with the RKI_COVID19.csv files issued by the Robert-Koch-Institut in Germany.

rki-covid19csv-parser

A small python module to work with the RKI_Covid19.csv files issued by the German RKI (Robert Koch Institut) on a daily basis.

Installation:

pip install rki-covid19csv-parser

Usage:

First steps:

Initialize the parser and load data from the RKI_Covid19.csv file. Because of the daily increasing file size this process can take a while.

import rki_covid19csv_parser

covid_cases = rki_covid19csv_parser.covid_cases()

covid_cases.load_rki_csv('path/to/csv')

Speeding up the loading process:

Once you have loaded the csv file it's possible to save the processed data to a file. This can speed up the process of loading the data significantly if you whish to run your script more than once.

#save file.
covid_cases.save_toFile('desired/path')

#load file.
covid_cases.load_fromFile('path/to/saved/file')
