Proper way to use iloc in Pandas

Question

I have the following dataframe df:

print(df)

    Food         Taste
0   Apple        NaN
1   Banana       NaN
2   Candy        NaN
3   Milk         NaN
4            


        

Answer 1

I prefer to use .loc in such cases, and explicitly use the index of the DataFrame if you want to select on position:

df.loc[df.index[0:2], 'Taste'] = 'good'
df.loc[df.index[2:6], 'Taste'] = 'bad'
