熊猫-使用将2行合并为1

Question

下面是我拥有的一个数据框的小例子。每个用户都有2行，我想将2行合并为1行。

（原始数据框）

USER       DETAIL          TEAM         VALUE
JohnDoe    Disponibily     Architect    107
JohnDoe    Capacity        Architect    240
JamesDean  Disponibily     Coder        80
JamesDean  Capacity        Coder        110

我正在尝试通过熊猫实现类似的目标：

USER       TEAM            Disponibily  Capacity
JohnDoe    Architect       107          240
JamesDean  Coder           80           110

任何帮助将不胜感激。

Answer 1

使用pivot_table

df = pd.DataFrame(data={"USER":["JohnDoe","JohnDoe","JamesDean","JamesDean"],
                       "DETAIL":["Disponibily","Capacity","Disponibily","Capacity"],
                       "TEAM":["Architect","Architect","Coder","Coder"],
                       "VALUE":[107,240,80,110]})
res = pd.pivot_table(df,index=['USER','TEAM'],columns='DETAIL',values='VALUE').reset_index()
res.columns.name = ''

        USER    TEAM    Capacity    Disponibily
0    JamesDean  Coder       110       80
1    JohnDoe    Architect   240       107
