I have two 2d list with large amount of rows and different size length for both lists.
I’m having trouble with finding only two matches in each sub-list in df1 and df2.
Let say I would like to find two matches from df1 in df2 I would like to return the matching values and non-matching values. which will probably convert into a 3d list then I would like to remove the bracket and convert it back to 2d list. If there’s a way to convert into 2d list without converting into 3d list first would help me out a lot.
