pandas通過索引獲取行值

In [1]: df = DataFrame(randn(5,2),index=range(0,10,2),columns=list('AB'))

In [2]: df Out[2]:            A         B  1.068932 -0.794307 -0.470056  1.192211 -0.284561  0.756029  1.037563 -0.267820 -0.538478 -0.800654

In [5]: df.iloc[[2]] Out[5]:            A         B -0.284561  0.756029

In [6]: df.loc[[2]] Out[6]:            A         B -0.470056  1.192211

綜上,iloc是按照index的序值. loc是按照index的具體值.
