Scraping data from Public Tableau

[nikedh]

Dear all.

I am collecting the Indian renewable energy data, and I am kinda stuck on gathering the data.

From the public Tableau, it seems that I can select the year and the tab.

But when I try to know the parameter or filter values to approach the yearly value, the results return nothing.

Here is my python code. I select only the worksheet of "Capacity by EnergySource".
(There are three worksheets in this data. I select only one worksheet for reference.)

But ultimately, I want to scrap the yearly data for all worksheets in each tab.

from tableauscraper import TableauScraper as TS

url = "https://public.tableau.com/views/RenewableCapacity/CapacitybySource"

ts = TS()
ts.loads(url)
workbook = ts.getWorkbook()

ws = ts.getWorksheet("Capacity by EnergySource")
print(ws.data)

ws.data.to_csv('table.csv',index=False)

parameters = workbook.getParameters()
print(parameters)

filters = ws.getFilters()
print(filters)

I am following each step of this thread and learning new ways to download the data from the public tableau.

Could anybody help on this issue?
