Pandas using row labels in boolean indexing

Question

So I have a DataFrame like this:

df = pd.DataFrame(np.random.randn(6, 3), columns=[\'a\', \'b\', \'c\'])

      a         b         c
0  1.877317  0.109646          


        

Answer 1

You nearly had it:

In [11]: df[(df.a > 0) & (df.index.isin([0, 2, 4]))]
Out[11]: 
          a         b         c
0  1.877317  0.109646  1.634978
4  0.214583 -0.856150 -0.477844
