iloc and loc

iloc 截取真实第几行的dataframe loc 截取dataframe中index为符合需要的dataframe

df = pd.DataFrame({'BoolCol': [True, False, False, True, True]},
       index=[10,20,30,40,50])

In [53]: df
Out[53]: 
   BoolCol
10    True
20   False
30   False
40    True
50    True

df.iloc[[0, 3, 4]]
df.loc[[10, 40, 50]]
