How can I sum a field within a chain RIC?

Looking to get the sum of OPINT_1 for an options chain RIC (0#KODK*.U) by puts and calls. I separated out the puts and calls into different lists. But I cannot find any instruction on how to now sum these values. As you can tell, I'm a beginner here. My goal is to look at the summed data in a time series.

fields = ['PUTCALLIND', 'STRIKE_PRC', 'OPINT_1']

kodk = ek.get_data('0#KODK*.U' , fields=fields)[0]

kodkputs = kodk[kodk['PUTCALLIND'] == 'PUT ']

kodkcalls = kodk[kodk['PUTCALLIND'] == 'CALL']

Use the "sum" method on pandas series:

op_int_puts = kodkputs['OPINT_1'].sum()

Hi @michael.t.smith

If you would like to know how to sum() the data on a dataframe.

Here is the dataframe document.

https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.sum.html

Here is the sample code:

kodkcalls['STRIKE_PRC'].sum()
