來自熊貓的關鍵錯誤

我在python中有以下代碼。來自熊貓的關鍵錯誤

d1=pd.read_excel("data1.xlsx",sheetname=0, index_col = "Time", parse_date=True) 
d1=d1.sort_index() 
for val in d1.columns: 
     start_his=d1[str(val)]

的data1.xlsx包含

Time  Start High Low  End  5 
05/12/2014 28,000 31,500 27,400 29,900 29,740.00 
28/11/2014 29,450 29,450 27,950 28,250 30,190.00 
21/11/2014 30,500 30,500 28,100 29,300 30,840.00 
14/11/2014 31,750 31,750 29,600 29,900 31,200.00 
07/11/2014 32,250 32,750 30,500 31,350 31,620.00 
31/10/2014 31,800 33,000 31,300 32,150 32,230.00 
24/10/2014 31,300 32,750 30,800 31,500 32,680.00 
17/10/2014 32,000 32,150 30,550 31,100 33,270.00 
10/10/2014 34,550 34,550 32,000 32,000 33,920.00 
02/10/2014 35,000 35,000 32,400 34,400 34,560.00 
26/09/2014 34,600 35,000 33,600 34,400 34,770.00 
19/09/2014 34,350 34,750 32,200 34,450 35,070.00

我輸出的第4列（啓動，高，低&完）但第5欄顯示關鍵錯誤。如果我將數字「5」更改爲任何其他值（即，Alpha數字），它將正常工作，但它不接受列標題中的數字。請幫助解決這個錯誤。

，我得到了錯誤的

這是因爲你正在使用'str（val）'而'5'將會成爲'5'''。直接使用'val'並回復結果 –

您正在使用str(val)和5將作出'5'。直接使用val：

d1=pd.read_excel("data1.xlsx",sheetname=0, index_col = "Time", parse_date=True) 
d1=d1.sort_index() 
for val in d1.columns: 
    start_his=d1[val]

我用d1 [val] .values嘗試過它工作...感謝您的回答... – Rajiv

@Rajiv不客氣 –
