我目前正在尝试使用python中的pandas将csv更改为数据帧并对其进行修改，以使其具有如下格式：
Year Country Serie1 Serie2 ...
Afganistan Something Something Something
1970 Columbia Sth Sth Sth
Zimbabwue S S S
其中年份是第一批国家只有一个数据的指数，第二批国家只有一个数据等。
我的数据来自：
https://github.com/antonio1695/Python/blob/master/CMU/GS.csv
我所做的代码是：
todo2=pd.read_csv("GS.csv")
todo2 = todo2.rename(columns = {'1970 [YR1970]':'1970'})
todo2 = todo2.rename(columns = {'1980 [YR1980]':'1980'})
todo2 = todo2.rename(columns = {'1990 [YR1990]':'1990'})
todo2 = todo2.rename(columns = {'1995 [YR1995]':'1995'})
todo2 = todo2.rename(columns = {'2000 [YR2000]':'2000'})
todo2 = todo2.rename(columns = {'2005 [YR2005]':'2005'})
todo2 = todo2.rename(columns = {'2010 [YR2010]':'2010'})
todo2 = todo2.rename(columns = {'2015 [YR2015]':'2015'})
GS1970 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '1970') # Pivotear como
GS1980 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '1980') # lo queriamos.
GS1990 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '1990')
GS1995 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '1995')
GS2000 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '2000')
GS2005 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '2005')
GS2010 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '2010')
GS2015 = todo2.pivot(index = 'Country Name',columns = 'Series Name', values = '2015')
GS1970['Year']=1970
GS1980['Year']=1980
GS1990['Year']=1990
GS1995['Year']=1995
GS2000['Year']=2000
GS2005['Year']=2005
GS2010['Year']=2010
GS2015['Year']=2015
GS = GS1970.append(GS1980).append(GS1990).append(GS1995).append(GS2000).append(GS2005).append(GS2010).append(GS2015)
GS.index.names=['Country']
GS=GS.set_index('Year','Country').sort_index()
它几乎完美无缺，但它给了我一个这样的数据框：
Year Serie1 Serie2 ...
Something Something Something
1970 Sth Sth Sth
S S S
正如您所看到的，Country缺少索引，我似乎无法添加它。我非常感谢你的帮助。
我将添加链接中的一些数据：
Country,Country Code,Series,Series Code,1970 [YR1970],1980 [YR1980],1990 [YR1990],1995 [YR1995],2000 [YR2000],2005 [YR2005],2010 [YR2010],2015 [YR2015]

todo2 = pd.read_csv("GS.csv")
todo2.columns = [re.sub(r'(\d+) \[YR\1\]', r'\1', col) for col in todo2.columns]
melted = pd.melt(todo2, id_vars=['Series Name', 'Country Name'], var_name='Year')
result = melted.set_index(['Series Name', 'Year', 'Country Name'])['value'].unstack('Series Name')
生成一个DataFrame，result，其MultiIndex为Year s和Country Name s，列索引为Series Name s。
In [53]: result.iloc[:3,:2].head()
Out[53]:
Series Name Age dependency ratio (% of working-age population) \
Year Country Name
1970 Afghanistan 88.12683234

而不是
todo2 = todo2.rename(columns = {'1970 [YR1970]':'1970'})
todo2 = todo2.rename(columns = {'1980 [YR1980]':'1980'})
todo2 = todo2.rename(columns = {'1990 [YR1990]':'1990'})
todo2 = todo2.rename(columns = {'1995 [YR1995]':'1995'})
todo2 = todo2.rename(columns = {'2000 [YR2000]':'2000'})
todo2 = todo2.rename(columns = {'2005 [YR2005]':'2005'})
todo2 = todo2.rename(columns = {'2010 [YR2010]':'2010'})
todo2 = todo2.rename(columns = {'2015 [YR2015]':'2015'})
你可以使用正则表达式替换：
todo2.columns = [re.sub(r'(\d+) \[YR\1\]', r'\1', col) for col in todo2.columns]
请注意todo2有列
In [50]: todo2.columns
Out[50]:
Index(['Series Name', 'Country Name', '1970', '1975', '1980', '1985', '1990',
'1995', '2000', '2005', '2010', '2015'],
dtype='object')
我们希望将Series Name，Country Name保留为列，并将年份标签放在新列中。此操作可以通过pd.melt：
melted = pd.melt(todo2, id_vars=['Series Name', 'Country Name'], var_name='Year')
id_vars=['Series Name', 'Country Name']指定要保留的列。所有剩余的列都“熔化”。请注意，我们现在有一个Year列：
In [51]: melted.head()
Out[51]:
Series Name Country Name Year \
0 Age dependency ratio (% of working-age populat... Afghanistan 1970
1 Age dependency ratio (% of working-age populat... Albania 1970
2 Age dependency ratio (% of working-age populat... Algeria 1970
3 Age dependency ratio (% of working-age populat... American Samoa 1970
4 Age dependency ratio (% of working-age populat... Andorra 1970
value
0 88.12683234
1 85.54006984
2 101.510271
3 ..
4 ..
我们差不多完成了。现在使用set_index将['Series Name', 'Year', 'Country Name']列移动到索引中，然后unstack Series Name索引级别。
result = melted.set_index(['Series Name', 'Year', 'Country Name'])['value'].unstack('Series Name')
unstack操作将索引级别移动到列级别。因此，您最终会得到来自Series Name的值的列。
答案 1 :(得分：0)
The above answer from unubtu有正确的方法。但是，回答你的原始问题
1）正确的语法是GS.set_index(['Year', 'Country'])而不是GS.set_index('Year', 'Country')，它将第二个位置参数设置为Country。不是你想要的。
2）Country是数据框GS的索引。
行GS.set_index(['Year', 'Country'])用于设置具有数据框列的索引。因此，需要Country作为列而不是索引。
另外，请勿指定GS.index.names。 Pandas使用该属性来保存MultiIndex标签和discourages direct access。请改用索引方法set_names。
