Question

我正在尝试编写通过For，In循环找到修改的.csv文件的整行。我已经设法让程序将密钥写入csv文件，但我无法将其与这些密钥一起写入关联值。我不确定我是否需要嵌套其他循环，或者我是否只是在语法上犯了错误。

import csv

def make_billing_dict(csv_dict_reader):
    bdict = {}
    for entry in csv_dict_reader:
    key = entry['BillingNumber']
    bdict[key] = entry
    return bdict

with open('old/MTBT.txt') as csv_file:
    old = csv.DictReader(csv_file)
    old_bills = make_billing_dict(old)

with open('new/MTBT.txt') as csv_file:
    new = csv.DictReader(csv_file)
    new_bills = make_billing_dict(new)

diff = file("diff/diff.csv", "wb" )
writer = csv.writer(diff)

for keys in old_bills:
    if old_bills[keys]['CustomerName'] != new_bills[keys]['CustomerName'] or old_bills[keys]['IsActive'] != new_bills[keys]['IsActive'] or old_bills[keys]['IsPayScan'] != new_bills[keys]['IsPayScan']:
        writer.writerow([keys])



#Used to send records to the console
#       print (new_bills[keys]['BillingNumber'],new_bills[keys]['CustomerName'],new_bills[keys]['IsActive'],new_bills[keys]['IsPayScan'],new_bills[keys]['IsCreditHold'],new_bills[keys]['City'],new_bills[keys]['State'])

#print set(new_bills.keys()) - set(old_bills.keys())

另外，我注意到如果我在新文件中添加一个新密钥和条目，它会导致没有问题，但如果我删除一条记录，则会导致密钥错误。我理解为什么，因为它正在寻找原始字典中的密钥，但有没有办法解决这个问题？

将完整记录写入For循环Python csvreader的.csv文件
