     You can pass a dictionary (to isin) with the values to search by column:

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

     Output

     A B0 True True1 False False2 False False-

     Afterwards you can find if the entry exists using all:

     result = df.isin({'A': [1], 'B': [4]}).all(1)print(result)-

     Output

     0 True1 False2 Falsedtype: bool-

     To use it in an if statement, and just on the columns ['A', 'B'], use any, for example:

     if df[['A', 'B']].isin({'A': [1], 'B': [4]}).all(1).any(): print('found')-

   • How do you check if anything is new in a list? (python)

     Top Answer

     Answered Oct 17, 2020 · 0 votes

     If you just care about the sets of values in list_1 and list_2, without regard to their order or the number of times they occur, then you can use a simple set difference:

     >>> list_1 = [10, 30, 25]>>> list_2 = [10, 25, 45]>>> list(set(list_2) - set(list_1))[45]>>>

     This example shows the values that are present in list_2 but not in list_1. To see values that were removed, you can reverse the subtraction.

     In general, the "Pythonic" philosophy for this kind of situation is called EAFP, for Easier to Ask for Forgiveness than Permission.
