Count occurrence of two elements in column of list

QUESTION

Count occurrence of two elements in column of list

Asked 2018-Jun-11 at 18:30

I have been struggling with this for a few days now. I read a lot online, found some similar questions such as: Pandas counting occurrence of list contained in column of lists or pandas: count string criteria across down rows but neither fully work in this case.

I have two dataframes: df1 consists of a column of strings. df2 consists of a column of lists (the lists are a combination of the strings from df1, each element within one list is unique).

I would like to know in how many lists of df2 occur each combination of strings. So, how many lists have "a" and "b" as elements? How many lists have "a" and "c" as elements and so forth.

This is how df1 looks like (simplified):

This problem is somewhat difficult because depending upon how many values you have, there can be a lot of pair-wise comparisons. I think you may want to create a dummy df with dummies for each value, and then you can use .all to easily query whatever pair-wise combination you want. It's also easy to generalize if you then want combinations of any number of elements.

First create the df_dummy which indicates whether that value is contained within the list.
