排序鍵

Question

我的代碼：

abc = { 
    'Name':emp_name, 
    'Id no':emp_idno, 
    'Leave taken':k, 
    'Leave reqd':b, 
    'Total days of leave':total, 
    'Reason':reason 
} 

我得到的輸出爲：

id, name, total, reqason, leave taken, leave reqd 

我所要的輸出是這個順序：

Name, id, leave taken, leave reqd, total, reason 

我對此很感興趣，如果有人能幫助我，這將是非常棒的。

我的CSV

碼

dl = {'Name':emp_name,'Id no':emp_idno, 'Leave taken':k, 'Leave 
> reqd':b, 'Reason':reason} 
>  
> 
>  key_list = ['Name', 'Id no', 'Leave taken', 'Leave reqd', 'Reason'] abc = { 'Name':emp_name, 'Id no':emp_idno, 'Leave taken':k, 
> 'Leave reqd':b, 'Reason':reason } 
> 
> for k in key_list: 
>  print abc[k] Lst.append(k) 
> 
> keys = Lst[0].keys() with open('employee.csv', 'wb') as output_file: 
>   dict_writer = csv.DictWriter(output_file, keys) 
>   dict_writer.writeheader() 
>   dict_writer.writerows(Lst) 

Answer 1

Dictionaries默認情況下無序。

您需要一個orderedDicitionary。

看到collections.OrderedDict

如：

from collections import OrderedDict 
d = OrderedDict() 
d['Name'] = emp_name 
d['Id no'] = emp_idno 
d['Leave taken'] = k 
print d 

Answer 2

一個簡單的黑客可以存儲在列表中的鍵。

key_list = ['Name', 'Id no', 'Leave taken', 'Leave reqd', 'Total days of leave', 'Reason'] 
abc = { 
'Name':emp_name, 
'Id no':emp_idno, 
'Leave taken':k, 
'Leave reqd':b, 
'Total days of leave':total, 
'Reason':reason 
} 

for k in key_list: 
    print abc[k]
