python - 在从 python 触发的电子邮件中将 pandas 数据框附加为 excel 文件

Question

我有一个熊猫数据框，它基本上是 sql 查询的结果。我想在从python触发的自动电子邮件中附加为xlsx，并且该excel文件应该提到数据框。如何才能做到这一点。

我可以成功发送没有附件的电子邮件，但不能发送附件。

import pandas as pd

data= pd.DataFrame(output of sqlquery) # this data is dataframe output of a sql query. 

# import necessary packages
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib
# create message object instance
msg = MIMEMultipart()
password = "password"
msg['From'] = "[e-mail]"
msg['To'] = "[e-mail]"
msg['Subject'] = "Messgae"
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
# Login Credentials for sending the mail
server.login(msg['From'], password)
server.sendmail(msg['From'], msg['To'], msg.as_string())

我不想从文件位置附加 excel 文件。首先，必须将该数据框写入excel，然后附加。

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders

fromaddr = '@gmail.com'
toaddr = ['@gmail.com', '@gmail.com', 
'@gmail.com']

msg = MIMEMultipart()

msg['From'] = fromaddr
msg['To'] = ", ".join(toaddr)
msg['Subject'] = "Hello"

body = "Sample Mail"

msg.attach(MIMEText(body, 'plain'))

filename = "Data.xlsx"
attachment = open("C:\\Users\\Desktop\\file.xlsx", 
"rb")

part = MIMEBase('application', 'octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % filename)

msg.attach(part)

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, "TYPEPASSWORD") #Type Password
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()
