Pandas compare columns of list

Question

I have columns in my DataFrame storing lists and I would like to compare each element in the column with a lists .

All the methods I have tried fails:

df.list_col == ['3', '4']
df.list_col.isin([['3', '4']])
df.list_col.equals(['3', '4'])

Is there a simple solution to this?

Answer 1

You can use apply with in :

df = pd.DataFrame({'A':[[1,2],[2,4],[3,1]],
                   'B':[4,5,6]})

print (df)
        A  B
0  [1, 2]  4
1  [2, 4]  5
2  [3, 1]  6

print (df.A.apply(lambda x: 2 in x))
0     True
1     True
2    False
Name: A, dtype: bool
