问题
我试图同时按两个不同的变量对数据框进行排序，我将以一个较小的子数据示例作为示例：
+---------------------------+-------------------+-----------------------+-------------------------+---------------------------+-----------------------+---------------------+------------------+
| | Caldisericumexile | Haloplasmacontractile | Chthonomonascalidirosea | Desulfurispirillumindicum | Chrysiogenesarsenatis | Gracilimonastropica | Balneolavulgaris |
+---------------------------+-------------------+-----------------------+-------------------------+---------------------------+-----------------------+---------------------+------------------+

+---------------------------+-------------------+-----------------------+-------------------------+---------------------------+-----------------------+---------------------+------------------+
所需的输出
我想用大熊猫沿着带有字母字符的列和沿着字母字符的行按字母顺序（降序）排序，例如：
+---------------------------+------------------+-------------------+-----------------------+-------------------------+---------------------------+---------------------+-----------------------+

+---------------------------+------------------+-------------------+-----------------------+-------------------------+---------------------------+---------------------+-----------------------+
是否可以在一行未命名的列和行的大熊猫中做到这一点？
答案 0 :(得分：1)
通过排序的索引和列名称使用reindex：
df = df.reindex(index=sorted(df.index), columns=sorted(df.columns))
print (df)

尝试使用直接设置列（表示[...]），然后对索引使用.T做同样的事情：
>>> import pandas as pd
>>> df=pd.DataFrame({'c':[1,2,3],'a':['a','b','c'],'b':[4,5,6]},index=list('bca'))
>>> df=df[sorted(df.columns.tolist())]
>>> df=df.T[sorted(df.index.tolist())].T
>>> df
a b c
a c 6 3
b a 4 1
c b 5 2
>>>
