问题描述
我使用 python 自动发送电子邮件,问题是有时代码有效,有时无效。
在代码中,python 基本上从 txt 中获取我的联系人,然后在另一个 txt 中获取我的电子邮件消息,并将消息从我的 txt 消息发送到存储在我的 contact.txt 中的联系人。
当问题大部分是我更新mycontacts.txt时出现的错误是:
Traceback (most recent call last):
File "c:/emailbot/botmessav1.py",line 70,in <module>
main()
File "c:/emailbot/botmessav1.py",line 36,in main
names,emails = get_contacts('mycontacts.txt') # read contacts
File "c:/emailbot/botmessav1.py",line 21,in get_contacts
names.append(a_contact.split()[0])
IndexError: list index out of range ```
以下是联系人列表的示例,mycontacts.txt

这是我正在使用的代码:
import smtplib
from string import Template
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
MY_ADDRESS = 'e-mail'
PASSWORD = 'password'
def get_contacts(mycontacts):
"""
Return two lists names,emails containing names and email addresses
read from a file specified by filename.
"""
names = []
emails = []
with open(mycontacts,mode='r',encoding='utf-8') as contacts_file:
for a_contact in contacts_file:
names.append(a_contact.split()[0])
emails.append(a_contact.split()[1])
return names,emails
def read_template(message):
"""
Returns a Template object comprising the contents of the
file specified by filename.
"""
with open(message,'r',encoding='utf-8') as template_file:
template_file_content = template_file.read()
return Template(template_file_content)
def main():
names,emails = get_contacts('mycontacts.txt') # read contacts
message_template = read_template('message.txt')
# set up the SMTP server
s = smtplib.SMTP(host='smtp.gmail.com',port=587)
s.starttls()
s.login(MY_ADDRESS,PASSWORD)
# For each contact,send the email:
for name,email in zip(names,emails):
msg = MIMEMultipart() # create a message
# add in the actual person name to the message template
message = message_template.substitute(PERSON_NAME=name.title())
# Prints out the message body for our sake
print(message)
# setup the parameters of the message
msg['From']=MY_ADDRESS
msg['To']=email
msg['Subject']="Subject"
# add in the message body
msg.attach(MIMEText(message,'plain'))
# send the message via the server set up earlier.
s.send_message(msg)
del msg
# Terminate the SMTP session and close the connection
s.quit()
if __name__ == '__main__':
main()
解决方法
contacts.txt 文件中不应有任何空行
