get_data for all RIC based on an option roots

Hello! Last week you helped me build out the open interest for a range of options for a particular root. But i actually need to go back a step further. (and achieve the same output). so the first try was great, and was as follows:

r, e = ek.get_data(instruments=['0#MCUZ8+'], fields=['X_RIC_NAME']) 
instruments = r['Instrument'].tolist()
instruments.pop(0)

r, e = ek.get_data(instruments=instruments, fields=['TR.OPENINTEREST(SDate=0,EDate=-7,Frq=D).date;TR.OPENINTEREST(SDate=0,EDate=-7,Frq=D)','DSPLY_NAME','EXPIR_DATE','CONTR_MNTH','STRIKE_PRC','TR.IMPLIEDVOLATILITY']) 


r.dropna()

All good. But the problem is that the option root i really need to examine is 0#MCU+

So as you can see on the screen shot below - the option root calls ALL of the open options - not just the month "Z" as i called in the code above. However, when I plug in the root - i just get blanks.

Is there a way of running teh script for the root and getting the same output - open interest, expir_date, strike_PRC ect ect ??

    Try something along the lines of:

    Get underlying instruments from 0#MCU+ chain

    request = tr.get_data(instruments=['0#MCU+'], fields=['X_RIC_NAME'])[0]

    Get all underlying instruments in a list of pandas data frames:

    dfs = [tr.get_data(instruments=[x], fields=['X_RIC_NAME','DSPLY_NAME'])[0] for x in request['Instrument'].tolist()]

    Parse out the list of options (every RIC longer than 6 chars):

    all_instruments = [x for df in dfs for x in df['Instrument'].tolist() if len(x) > 6]

    Please note that for simplicity I am not checking the error object, so such code can not be used in production.
