Question

            total_purchase_amt
2013-07-01            22533121
2013-07-02            29624840
2013-07-03            22525940
2013-07-04            32111643
...                        ...

我需要删除2行(2013-07-02 29624840)，我该怎么做？

Answer 1

使用drop方法

In [8]: df.drop(['2013-07-02'])
Out[8]:
            total_purchase_amt
2013-07-01            22533121
2013-07-03            22525940
2013-07-04            32111643

这里的初始df是

In [9]: df
Out[9]:
            total_purchase_amt
2013-07-01            22533121
2013-07-02            29624840
2013-07-03            22525940
2013-07-04            32111643
