Python/R：删除重复行-保留唯一的作者对

这是我从数据库中提取的一个示例。我在合作作者中使用可视化，所以基于此示例，我必须在两位作者中保持一种关系。例如，我必须删除布赖恩·诺顿中的一个---玛丽亚·鲁昂或玛丽亚·鲁昂---布赖恩·诺顿，以保持关系的唯一性

在这种情况下，我只想保持一排。在R或Python中如何处理它？

非常感谢您的帮助。

我假设您有一个单独的数据库，并且正在使用python与之连接

可能的办法：

1） 您可以根据

文章

列添加行号，然后执行重复数据消除。您可以查看答案，了解如何在SQL中实现它

然后，您可以使用python-db连接器运行查询

---

2） 您可以将记录拉入pandas数据框并在其中进行分析。善于处理和操纵数据。

我假设您的数据帧与我在下面展示的数据帧类似，因为您没有分享可能出现的其他可能性

article author1 author2
A       a       b
A       b       a
A       a       a
A       b       b

在R中，这就是如何获取您要查找的行的方法。我假设您的数据帧是

df1

# This will create a new dataframe df2 with only those rows where author1 and author2 are different

df2 <- df1[df1$author1 != df1$author2, ]

---

如果这是您需要的，请告诉我。

到目前为止，您有没有尝试过什么？您正在使用库/包吗？（Numpy/Pandas代表Python，dplyr或datatables代表R）谢谢你的回答，但我的问题不是删除重复列，问题是如果author1和author2在同一篇文章中具有相同的值但顺序不同，如何删除重复项。当你说相同的值时，你是说

author1

和

author2

都应该是

a

？不，这意味着在同一篇文章中，我只需要一条记录，如：文章a author1a author2b或文章a author1b author2查看我的更新答案。由于您没有为我提供更大的数据集来全面测试我的代码，我假设

author1

和

author2

将只包含

a

或

b

。如果这能帮你解决问题，请告诉我。非常感谢你的帮助。谢谢，我会努力的。

article author1 author2
  A       a       b
  A       b       a
