within the list cited_docdb_list, however, there are ids that do not appear id docdb_family_id. What I would like to do is to detect the number of ids within cited_docdb_list which also appear in docdb_family_id. Is there a way to do so? My df is very large actually (almost 700000 observations). Please notice that the type of docdb_family_id and cited_docdb_list differs in the data.

The expected outcome, for instance for the first couple of docdb_family_ids should be:

docdb_family_id nb_included
3498148,            2
3512921,            1
...

where 3498148, 2 comes from the fact that the cited_docdb_list related to 3498148 cites 2 indices that appear in docdb_family_id, namely 3802281 and 3944218. In the same fashion, 3512921 cites 3800683 within cited_docdb_list.

Thank you

First idea is test intersection of sets with converted lists of strings to list of integers and get length of sets for nb_included:

import ast

df['cited_docdb_list'] = df['cited_docdb_list'].apply(ast.literal_eval)


sets = set(df['docdb_family_id'])
df['nb_included']=[len(set(map(int,x)).intersection(sets)) for x in df['cited_docdb_list']]

print (df)
