ANSWER

Answered 2021-Feb-18 at 23:52

Since movies is a list of dictionaries (which are unhashable), converting it to a set to get rid of duplicates will not work. Instead you have to iterate and append each movie to the movies list on the condition that it does not already exist there. You have already tried to do this with the if statement inside the for loop. The problem is that your if statement is always True because your are checking just for a Title and not for the whole dictionary object. You can fix it like this:

How to groupby a column which contains a list

This is the code:

ANSWER

Answered 2021-Jan-28 at 04:44

'tickers' is a column of str type, not list type, so they can be converted to list type, by using ast.literal_eval with the converters parameter.
The values in the lists in the 'tickers' column can be removed from the lists, by using the .explode method.
In order to properly .groupby the date, the 'time' column must be converted to a datetime dtype.
