將打印輸出寫入csv文件

Question

我需要編寫代碼以將輸出打印到csv文件的幫助。 該代碼發布在下面。 感謝您的幫助。

import csv

result = {}

with open('data.csv', 'rb') as csvfile:
    csvreader = csv.reader(csvfile, delimiter=',', quotechar='"')
    for row in csvreader:
        if row[0] in result:
            result[row[0]].append(row[1])
        else:
            result[row[0]] = [row[1]]

print result

使用csv.writer將result的行寫入輸出流：

with open('output.csv', 'w') as csvfile:
    csvwriter = csv.writer(csvfile)
    for row in result.items():
        csvwriter.writerow(row)
