python中series转dataframe的两种方法

In [21]: df2 = df1.loc[1].to_frame()                                                                                    

In [22]: df2                                                                                                            

Out[22]:

       1

id     2

name 

In [23]: df3 = pd.DataFrame(df2.values.T,columns=df2.index)                                                             

In [24]: df3                                                                                                            

Out[24]:

  id name

0  2   李四

In [25]: df1                                                                                                            

Out[25]:

  id name

0  1   张三

1  2   李四

2  3   王五

for i ,j in df.iterrows():

    j=pd.DataFrame([j.to_dict()]) #series有转frame dict等方法

    print(j)

    print(type(j))

    print(j['age'])
