使用 Python Dict 发送带有特定附件的电子邮件

Question

我有一个 python 字典：

df.set_index('EMAIL').to_dict()['ID'] 
   
email_group = {'test1@test.com': 'ID1.xlsx',
               'test2@test.com': 'ID2.xlsx',
               'test3@test.com': 'ID3.xlsx'
                   }

预期结果：我想将ID1.xlsx附加到第一个电子邮件地址并发送，将ID2.xlsx到第二个电子邮件地址并发送，最后将ID3.xlsx到第三个电子邮件地址并发送。

以下代码产生错误“名称'文件'未定义”。 我缺少什么才能获得上述预期结果？

class EmailsSender:
        def __init__(self):
            self.outlook = win32.Dispatch('outlook.application')
    
        def send_email(self, to_email_address, attachment_path):
            mail = self.outlook.CreateItem(0)
            mail.To = to_email_address
            mail.Subject = 'Report'
            mail.Body = """Report is attached."""
            if attachment_path:
                mail.Attachments.Add(Source=attachment_path)
            mail.Send()
    
        def send_emails(self, email_group, attachment_path=None):
            for email, file in email_group.items():
                self.send_email(email, attachment_path + file)
    
    attachment_path = r'C:\Users\Desktop\Test'
    email_sender = EmailsSender()
    email_sender.send_emails(email_group, attachment_path + file)

Answer 1

我认为你需要改变

email_sender.send_emails(email_group, attachment_path + file)

到

email_sender.send_emails(email_group, attachment_path)

解释会抱怨，因为这里没有声明file 。
