将另一个csv值列表追加到另一列

Question

我正在尝试将另一行值附加到另一列中。这是我第一次使用python，我已经参考了几篇文章，但是我没有设法使其工作。

下面是我的代码段，您可以看到savetoCSV()写入文件，然后saveQIDtoCSV()附加到文件。

我正在尝试实现以下输出，即2个单独列中的值。

Name       ID

我的代码：

def savetoCSV(detectionItems,filename):

    # specifying the fields for csv file
    fields = ['HOST_LIST', 'DATETIME', 'QID', 'IP', 'TRACKING_METHOD', 'media']
    lstdetectionItems=[detectionItems]
    #lstQID = [qid]
    # writing to csv file
    with open(filename, 'w' , newline= '') as csvfile:

        # creating a csv dict writer object
        writer = csv.writer(csvfile,delimiter='\n')

        for qid in lstdetectionItems:
            writer.writerows(lstdetectionItems)

def saveQIDtoCSV(qid, filename):

    # specifying the fields for csv file
    fields = ['HOST_LIST', 'DATETIME', 'QID', 'IP', 'TRACKING_METHOD', 'media']
    lstdetectionItems=[qid]

    # writing to csv file
    with open(filename, 'a' , newline= '') as csvfile:

        # creating a csv dict writer object
        writer = csv.writer(csvfile,delimiter=',')

        for qid in lstdetectionItems:
                f1= open(filename,'r')
                reader=csv.reader(f1)
                for row in reader:
                        row[1] = f1.readline()
                        writer.writerow(row)
