#2种排序一种是按标签一种是按值
#按标签排序 unsorted_df=pd.DataFrame(np.random.randn(10,2),index=[1,4,6,2,3,5,9,8,0,7],columns=[‘col2‘,‘col1‘]) print (unsorted_df) unsorted_df=unsorted_df.sort_index() print (unsorted_df)
#按值排序 sorted_df = pd.DataFrame({‘col1‘:[2,1,1,1],‘col2‘:[1,3,2,4]}) print (sorted_df) sorted_df = sorted_df.sort_values(by=‘col1‘,kind=‘mergesort‘,ascending=True) print (sorted_df)
