Hi
I have a csv file like this V0,V1,V2,V3 4,1,1,1 6,4,5,2 2,3,6,7 And I want to search two rows for a match and find the column. For example, I want to search row[0] for 1 and row[1] for 5. The corresponding column is V2 (which is the third column). Then I want to return the value at row[2] and the found column. The result should be 6 then. I can manually extract the specified rows (with index 0 and 1 which are fixed) and manually iterate over them like arrays to find a match. Then I key1 = 1 key2 = 5 row1 = df.iloc[0] # row=[4,1,1,1] row2 = df.iloc[1] # row=[6,4,5,2] for i in range(len(row1)): if row1[i] == key1: for j in range(len(row2)): if row2[j] == key2: res = df.iloc[:,j] print(res) # 6 Is there any way to use built-in function for a more efficient code?
