如何以相反的顺序迭代熊猫系列?
常规迭代是:
for index, value in series.items():
如何反向操作,类似于:
for index, value in reversed(series.items()):
您可以反转Series
,如下所示:
In [251]: s = pd.Series([0,1,2])
反转:
In [252]: s.iloc[::-1]
Out[252]:
2 2
1 1
0 0
要迭代它,你可以这样做:
In [254]: for ix, val in s.iloc[::-1].items():
...: print(val)
...:
2
1
0
