pandas 数据框按列排序 [英] Pandas Dataframe sort by a column

问题描述

我有一个Python Pandas数据框. df有2列，我想按第二列对df进行排序.

I have a Python Pandas Data Frame. The df has 2 columns, I would like to sort the df by the second column.

   Kappa_prod   Angle
0   0.004511    -5.457840
1   0.003977    -5.312861
2   0.004476    -5.311292
3   0.003644    -117.579594
4   0.003306    -117.542817

我想按角度对df排序(升序).

I would like to sort the df by Angle (ascending order).

推荐答案

您可以使用:

df.sort_values("Angle", inplace=True)

默认情况下，ascending=True被传递给上述调用.有关更多信息，请在文档此处.

By default ascending=True is passed to the above call. For more information check the documentation here.
