Score	Grade1	Grade2	Grade3	Grade4
<260	A1	IA1	D1	ID1
260-275	A2	IA2	D2	ID2
275-280	A3	IA3	D3	ID3
280-285	A4	IA4	D4	ID4
>=285	A5	IA5	D5	ID5

Input :-

Score	Grade1	Grade2	Grade3	Grade4
290	A1	IA4	D3	ID2

Example

data1 = {'Grade': {0: 'B1', 1: 'B2', 2: 'B3', 3: 'B4', 4: 'B5'},
         'Grade1': {0: 'A1', 1: 'A2', 2: 'A3', 3: 'A4', 4: 'A5'},
         'Grade2': {0: 'IA1', 1: 'IA2', 2: 'IA3', 3: 'IA4', 4: 'IA5'},
         'Grade3': {0: 'D1', 1: 'D2', 2: 'D3', 3: 'D4', 4: 'D5'},
         'Grade4': {0: 'ID1', 1: 'ID2', 2: 'ID3', 3: 'ID4', 4: 'ID5'}}
data2 = {'Grade': {0: 'B5'}, 'Grade1': {0: 'A1'}, 'Grade2': {0: 'IA4'},
         'Grade3': {0: 'D3'}, 'Grade4': {0: 'ID2'}}
df1 = pd.DataFrame(data1)
df2 = pd.DataFrame(data2)

Code

make condition by using broadcasting

df1[df1.eq(df2.iloc[0])]

result:

    Grade   Grade1  Grade2  Grade3  Grade4
0   NaN     A1      NaN     NaN     NaN
1   NaN     NaN     NaN     NaN     ID2
2   NaN     NaN     NaN     D3      NaN
3   NaN     NaN     IA4     NaN     NaN
4   B5      NaN     NaN     NaN     NaN
