Python 循环不完全遵守既定规则

Question

我希望尽快根据共享 Outlook 邮箱中的发件人标记电子邮件。

#imports:
import time
from time import strftime
import pandas as pd, win32com.client as client
from win32.com.client import Dispatch

#importing the excel file that contains email addresses and corresponding flags:
df_excel = pd.read_excel(r'\user\...\addresses.xlsx')
#adding both columns as lists:
df_excel_mail = df_excel['mail'].tolist();df_excel_flag = df_excel['flag'].tolist()
outlook = client.Dispatch('Outlook.Application').GetNamespace('MAPI')
main_account = outlook.Folders.Item(1)
folder_inbox = main_account.Folders['Inbox'].Folders['Test']
folder_inbox_WIP = main_account.Folders['Inbox'].Folders['Test'].Folders['WIP']

while True:
    time.sleep(0)
    messages = folder_inbox.Items.Count
    if messages > 0:
        for i in reversed(range(0,messages)):
            message = folder_inbox.Item[i]
            for y, z, in zip(df_excel_mail,df_excel_flag)
                if message.Categories == '' and y == message.SenderEmailAddress
                    message.Categories = z
                    message.Save
                    message.Move(folder_inbox_WIP)

    messages_v2 = folder_inbox_WIP.Items.Count
    if folder_inbox_WIP .Items.Count > 0:
        for ii in reversed (range(0,messages_v2)):
            message_v2 = folder_inbox_WIP[ii]
            message_v2.Move(folder_inbox)

    if strftime('%H, %M, %N') >= strftime('18:00:00')
        break

我的addresses.xlsxsheet看起来是这样的：

邮件	旗帜
aaa.bbb@mail.com	红色
ccc.ddd@outlook.com	绿色
...	...
eee.fff@client.com
...	...

当电子邮件地址在 df_excel_mail 列表中可用但在 df_excel_flag 列表中缺少相应的标志颜色时。有些电子邮件无论如何都会发送到 WIP 文件夹并标记为#QNAN。

当以下代码本应防止这种情况发生时，这怎么可能？

if message.Categories == '' and y == message.SenderEmailAddress

Answer 1

问题与数据框中的 'NaN' 值有关，我使用 .notna() 来修复它
