Pandas将重复索引合并为单个索引

我有一个像这样的简单数据框：

d1={'a':{'1998-01-01':10}}
d2={'b':{'1998-01-01':3}}

df=pd.DataFrame.from_dict(d1)
df=df.append(pd.DataFrame.from_dict(d2))
df.index=pd.to_datetime(df.index)

             a   b
1998-01-01  10 NaN
1998-01-01 NaN   3

我想

             a   b
1998-01-01  10   3

自1998-01-01以来共享指数

2 个答案:

答案 0 :(得分：4)

或者您可以index level=0方式使用groupby - 参数print df.groupby(level=0).sum() a b 1998-01-01 10 3 与sum：

print df.sum(level=0)

或更好：

答案 1 :(得分：2)

或者你也可以试试这个（用原始数据框）：

print(df)
print(df.groupby(df.index).sum())

输出：

             a   b
1998-01-01  10 NaN
1998-01-01 NaN   3
             a  b
1998-01-01  10  3
