对数据框的所有列进行排序

对数据框的所有列进行排序

我认为您可以

numpy.sort

与

Dataframe

构造函数

apply

一起使用，也可以

sort_values

与convert to

numpyarray

by一起使用

values

：

df = pd.Dataframe(np.sort(df.values, axis=0), index=df.index, columns=df.columns)

另一个解决方案，速度较慢：

df = df.apply(lambda x: x.sort_values().values)print (df)      0    1    2    3    4    5    6    7    8    9   ...   490  491  492         0    0    0    0    0    0    0    0    0    0 ...     0
