CSV WriteRow數據

Question

我想寫2個變量到我的CSV中的行。 result變量（它有2列/值）和'item variable (which has just 1 value). Can I include both of these values in the writerow`函數參數？如果是這樣，語法將如何顯示？我的語法如下，兩個變量之間的逗號不起作用。

行我說的是：

writer.writerow([item,result.items()[0][0],result.items()[0][1]]) 

的所有代碼：

#!/usr/bin/env python 

import splunklib.client as client 
import splunklib.results as results 
import csv 

listOfAppIDs = [] 
with open('filefolder/filelocation.txt', 'r') as fi: 
    for line in fi: 
     listOfAppIDs.append(line.rstrip('\n')) 
listOfAppIDs.sort() #alphebetically sort list 

HOST = "ipAddress" 
PORT = 1234 
USERNAME = "uName" 
PASSWORD = "pWord" 

startPoint = "firstAppInList" 

outputCsv = open('filefolder/filelocation.csv', 'wb') 
fieldnames = ['appID', 'TotalDestinationIPAddresses', 'AverageThroughputPerMonth'] 
writer = csv.DictWriter(outputCsv, fieldnames=fieldnames) 
writer.writeheader(); 

def connect(): 
    global startPoint , item 

    service = client.connect(
     host=HOST, 
     port=PORT, 
     username=USERNAME, 
     password=PASSWORD, 
     autologin=True 
    ) 

    jobs = service.jobs 
    kwargs_blockingsearch = {"exec_mode": "blocking"} 

    try: 
     for item in listOfAppIDs: 
      if (item >= startPoint): 
       searchquery_blocking = "splunkQuery" 
       print item + ':' 
       job = jobs.create(searchquery_blocking, **kwargs_blockingsearch) 
      for result in results.ResultsReader(job.results()):    
       writer.writerow([item,result.items()[0][0],result.items()[0][1]])#writes data underneath the column header 
    except csv.Error: 
     startPoint = item 
     connect() 

connect() 
outputCsv.close() 

答：

writer.writerow([item,result.items()[0][1],result.items()[1][1]]) 

Answer 1

您可以通過將一個數組傳遞多個領域writerow。假設result是兩個元素的數組，你可以這樣做

writer.writerow([item,result[0],[result[1]]) 

，或者result是OrderedDict，按您的評論，你可以這樣做：

writer.writerow([item,result.items()[0][0],result.items()[0][1]]) 

Answer 2

什麼錯誤訊息您收到？

使用csv.DictWriter時應將字典傳遞給writerow()，而不是列表。根據我所看到的，您可以使用正常的csv.writer對象，並且只需將writerow()與您的標題行一起使用，而不是爲每個writerow()調用創建一本字典。

所以，如果你初始化像這樣，我認爲它會工作：

writer = csv.writer(outputCsv) 
writer.writerow(fieldnames);
