我是R编程的新手,并且在满足过滤条件后尝试删除每组行中的某些行.

场景:对于每个GROUP,如果2个TYPE"B"在一行中,则删除该GROUP的所有以​​下行."Include in DataSet"列显示输出应该是什么.

这是我的示例输入:

GROUP   TYPE    Include in DataSet?
--------------------------------------------
1       A       yes
1       A       yes
1       B       yes
1       B       yes
1       B       no
2       A       yes
2       B       yes
2       B       yes
2       A       no
2       B       no
2       B       no

DF = structure(list(GROUP = c(1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 
2L, 2L), TYPE = c("A", "A", "B", "B", "B", "A", "B", "B", "A", 
"B", "B"), inc = c("yes", "yes", "yes", "yes", "no", "yes", …

我想删除列动物每行中的重复项。

我需要类似这篇文章的内容，但需要使用python。由于某种原因，我现在无法解决此问题，并且遇到了障碍。

删除数据框中的重复记录

我试过使用掉落重复项，唯一性，唯一性等。没有运气。

df.drop_duplicates（subset = None，keep =“ first”，inplace = False）df

df = pd.DataFrame ({'animals':['pink pig, pink pig, pink pig','brown cow, brown cow','pink pig, black cow','brown horse, pink pig, brown cow, black cow, brown cow']})

#input:
    animals
0   pink pig, pink pig, pink pig
1   brown cow, brown cow
2   pink pig, black cow
3   brown horse, pink pig, brown cow, black cow, brown cow

#I would like the output to look like this:
    animals
0   pink pig
1   brown …
