使用 Pandas，为什么列/系列标题没有显示在输出的顶部 [英] Using Pandas, why is the column/series header not showing at the top of an output

问题描述

在:

def answer_three():
    Top15 = answer_one()
    
    #https://stackoverflow.com/questions/51826751/average-of-dataframe-columns
    
    Top15['avgGDP'] = Top15[['2006', '2007', '2008', '2009', '2010', '2011', '2012', '2013', '2014', '2015']].mean(axis=1)
    Top15 = Top15.sort_values('avgGDP', ascending=False)
    
    return Top15['avgGDP']

answer_three()

出:

Country      
UU           15368
CF            6348
J             5542
G             3493
F             2681
UT            2487
B             2189
IA            2120
IB            1769
CG            1660
R             1565
S             1418
A             1164
S             1106
T             7704
Name: avgGDP, dtype: float64

观察:

标题/系列名称与数据类型一起显示在底部.我已经研究过但找不到答案，只添加/重命名标题，只提取标题等.这不是我的问题，我只是希望输出在我正常调用数据帧时看起来，但只有这个选择/单一字段在这种情况下，即我想要:

The header/series name shows at the bottom along with the datatype. I have researched and can't find the answer, only adding/renaming headers, extracting only headers, etc. That is not my problem, I simply want the output to look when I call a dataframe normally, but only this select/singular field in this case, i.e. i want:

Country      avgGDP
UU           15368
CF            6348
J             5542
G             3493
F             2681
UT            2487
B             2189
IA            2120
IB            1769
CG            1660
R             1565
S             1418
A             1164
S             1106
T             7704

我在输出全帧之间看到的唯一不同之处在于我请求的是单个特定列.我假设我必须在我的 return 语句中添加一些东西，所以它输出就像我调用了一个完整的数据框.

The only thing I see different between output a full frame and this is that I am requesting a single specific column. I am assuming I have to add something to my return statement, so it output like I called a full dataframe.

非常感谢您的时间和帮助！

I appreciate your time and assistance in advance!

谢谢，

推荐答案

系列名称始终显示在系列下方.DataFrame 列名称显示在列上方.您可以将系列转换为单列 DataFrame:

A Series name is always shown under the Series. A DataFrame column name is shown above the column. You can convert the Series into a one-column DataFrame:

pd.DataFrame(Top15['avgGDP'])

它将按照您的预期显示.

It will be displayed as you expect.
