Hi,
I want to get the ISIN from a list of delisted RICS (not all but the majority).
From the help desk I got this answer, to get delisted information.
=@TR($B$2,"TR.ISIN","SDate=2021-03-31 EDate=2021-03-31 CH=Fd",$C$2)
Is it possible to prompt it via Python? How to handle the fact that for each RIC, I have a specific SDate and EDate.
The df looks something like this

So far, I have this.
df_isin = ek.get_data(df['Ric'],fields="TR.ISIN", parameters = {'SDate':df['Sdate'], 'EDate': df['Edate']})
