所以我在csv中有一个这样的样本数据集: -
name team date score
John A 3/9/12 100
John B 3/9/12 99
Jane B 4/9/12 102
Peter A 9/9/12 103
Josie C 11/9/12 111
Rachel A 30/10/12 98
Kate B 31/10/12 103
David C 1/11/12 104
执行以下操作:-
from pandas.io.parsers import read_csv
df = read_csv("data/Workbook1.csv", index_col=["team", "name"])
df
date score
team name
A John 3/9/12 100
B John 3/9/12 99
Jane 4/9/12 102
A Peter 9/9/12 103
C Josie 11/9/12 111
A Rachel 30/10/12 98
B Kate 31/10/12 103
C David 1/11/12 104
如何进一步压缩第一个索引(“团队”)以使我没有重复值?成为:-
date score
team name
A John 3/9/12 100
Peter 9/9/12 103
Rachel 30/10/12 98
B John 3/9/12 99
Jane 4/9/12 102
Kate 31/10/12 103
C Josie 11/9/12 111
David 1/11/12 104
