[Dashboard rest API] How to change exporting date from Results from an Existing Chart in python?

Hi All

I am new to coding API, i am trying to export data from a existing chart, i try to fallow this document to do it, my goal is to export the data for everyday for further analysis.
https://developers.amplitude.com/docs/dashboard-rest-api#results-from-an-existing-chart

my question is how do i setup date range parameter in my python code in order to export data from a different date range? 

thanks in advance,
mike
