我想用datetime set_index dateFrame

poorList = [datetime.date(2016, 5, 2), 
            datetime.date(2016, 8, 26), 
            datetime.date(2016, 6, 9), 
            datetime.date(2016, 3, 4)]

dateForm.set_index(poorList)

那是错误的：

File “pandas\index.pyx”, line 137, in pandas.index.IndexEngine.get_loc
(pandas\index.c:4066)
File “pandas\index.pyx”, line 159, in pandas.index.IndexEngine.get_loc (pandas\index.c:3930)
File “pandas\hashtable.pyx”, line 675, in pandas.hashtable.PyObjectHashTable.get_item (pandas\hashtable.c:12408)
File “pandas\hashtable.pyx”, line 683, in pandas.hashtable.PyObjectHashTable.get_item (pandas\hashtable.c:12359)
KeyError: datetime.date(2016, 5, 2)

请告诉我该怎么做？

解决方法:

DataFrame.set_index()需要将列名或列列表作为参数,因此您应该执行以下操作：

dateForm['date'] = poorList
dateForm.set_index('date', inplace=True)
