问题
我试图同时通过两个不同的变量来订购数据帧，我将发布我的数据帧的一个小子样本作为示例:
+---------------------------+-------------------+-----------------------+-------------------------+---------------------------+-----------------------+---------------------+------------------+

所需输出
我想使用 pandas 沿包含字母字符的列和包含字母字符的行按字母顺序(降序)排序，例如:
+---------------------------+------------------+-------------------+-----------------------+-------------------------+---------------------------+---------------------+-----------------------+

是否可以在 pandas 中使用未命名的列和行在一行中执行此操作？
最佳答案
使用reindex按排序索引和列名称:
df = df.reindex(index=sorted(df.index), columns=sorted(df.columns))
print (df)
