我对熊猫有点陌生，现在我有一个问题

我从一个html网站上读取一个表格，并根据网站上的表格设置标题

 df = pd.read_html('http://www.espn.com/nhl/statistics/player/_/stat/points/sort/points/year/2015/seasontype/2', header = 1)

现在我有了带有匹配头的my dataframe，但我有一些行与头相同，如下面的示例

RK                  PLAYER  TEAM  GP   G   A  PTS  +/-  PIM  PTS/G  SOG 
1          Jamie Benn, LW   DAL  82  35  52   87    1   64   1.06  253   
2         John Tavares, C   NYI  82  38  48   86    5   46   1.05  278   
...      
10  Vladimir Tarasenko, RW   STL  77  37  36   73   27   31   0.95  264   
RK                  PLAYER  TEAM  GP   G   A  PTS  +/-  PIM  PTS/G  SOG 
14       Steven Stamkos, C    TB  82  43  29   72    2   49   0.88  268

我知道可以使用panda删除重复的行，但是否可以删除与标题或特定行重复的行

希望你能帮助我

您可以使用：

如果需要，还可以删除列

PLAYER

中带有

PP

的行，请使用：

注意：我将

[0]

添加到

read\u html

的末尾，因为它返回数据帧列表，您需要选择列表的第一项：
