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

Purely integer-location based indexing for selection by position.. eg :-

lang_sets = {}
lang_sets['en'] = train[train.lang == 'en'].iloc[:,:-1]
lang_sets['ja'] = train[train.lang == 'ja'].iloc[:,:-1]
lang_sets['de'] = train[train.lang == 'de'].iloc[:,:-1]
