我正在写一个python脚本来发送电子邮件。现在它正在发送一个excel文件作为附件，但我想发送带有excel文件内容的正文的电子邮件。就像使用颜色，格式化等复制excel文件的内容并将其粘贴到电子邮件正文中一样。我该怎么做？
我的python脚本如下：
#!/usr/local/bin/python2.7
import smtplib,email,email.encoders,email.mime.text,email.mime.base
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email import encoders
from email.message import Message
from email.mime.audio import MIMEAudio
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import schedule
import time
msg = MIMEMultipart()
# me == my email address
# you == recipient's email address
me = "abc@something.com"
you = "abc@something.com"
# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('mixed')
msg['Subject'] = "Automation Testing"
msg['From'] = me
msg['To'] = you
# Create the body of the message (a plain-text and an HTML version).
text = "Hi\n\nPlease find attached the weekly report."
part1 = MIMEText(text, 'plain')
#attach an excel file:
fp = open('/Users/excel.xlsm', 'rb')
file1=email.mime.base.MIMEBase('application','vnd.ms-excel')
file1.set_payload(fp.read())
fp.close()
email.encoders.encode_base64(file1)
file1.add_header('Content-Disposition','attachment;filename=excelsheet.xlsx')
# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(file1)
composed = msg.as_string()
fp = open('msgtest.txt', 'w')
fp.write(composed)
# Credentials (if needed)
# The actual mail send
server = smtplib.SMTP('smtp.something.com', 259)
server.starttls()
server.sendmail(me, you, composed)
server.quit()
fp.close()
