I have two dataframe df



df1



I need to compare both dataframe and my output should in such a way that if the values a df1 is present in df leave it as it is else it should be replaced by Out. For example values of column in Level_count should be like L1,L1,L1,L2,L2,L2,L2,Out,Out,Out (as L3 and l4 are not in df1) like this same way i need to compare Edu and Occ as well.



This is my desired output
Output
Could anyone help me in solving out this solution.

You need:



df2_dict=df2.to_dict(orient='list')
# {'Level_Count': ['L1', 'L2'], 'Edu': ['MBBS', None], 'Occ': ['MBBS1', None]}

for c in df1.columns:
df1[c]=df1[c].apply(lambda x: x if x in df2_dict[c] else 'out')


Output:



    Level_Count Edu Occ
0 L1 MBBS MBBS1
1 L1 MBBS MBBS1
2 L1 out out
3 L2 MBBS MBBS1
4 L2 MBBS MBBS1
5 L2 MBBS MBBS1
6 L2 MBBS MBBS1
7 out MBBS MBBS1
8 out out out
9 out MBBS MBBS1
