How to send Pandas DataFrame as an attachment in Pandas - python-3.x

Question

I have searched around SO and Google a lot but did not get my answer hence ultimately thought to ask here.
I have a csv file, which I'm converting to an html frame which works fine and I can send that as an html frame via Outlook as an email.
Was looking if we can directly send df.to_html as an attachment to the e-mail ?
Below is the code:
This works fine sending as an e-mail with html frame via Outlook.
import pandas as pd
import numpy as np
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
df = pd.read_csv('graph.csv', names=['Volume_Path', 'Last Acced', 'Year', 'Month', 'Days', '1-24 hrs', '1 hour', '15 mins', 'future'])
df['Volume_Path'] = df['Volume_Path'].str.replace('\t', '')
df = df.replace(np.nan, '')
# Create message container - the correct MIME type is multipart/alternative.
##############################################################################
msg = "<u><b> Checklist</b></u><br />"
msg = msg + "<br />"
msg += df.to_html(escape=False)
def mail(msg,recipients,key):
try:
s = smtplib.SMTP('mailserver.xyz.com')
msg1 = MIMEText(msg, 'html')
sender = 'tina#xyz.com'
msg1['From'] = sender
msg1['To'] = ", ".join(recipients)
msg1['Cc'] = 'mauj#xyz.com'
msg1['Subject'] = "Mauj Test"
s.sendmail(sender, recipients, msg1.as_string())
print(f"Mail Sent to {sender}")
except Exception as error:
print(f"Mail Failed - {error}")
recipients = ['joe#xyz.com']
key=""
mail(msg,recipients,key)

If you don't want to save the pandas.DataFrame as an html file on your drive but rather attach it directly I would use MIMEBase and attach it to your message
Here html_object is the df.to_html() object.
import smtplib
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
def mail(body,recipients,key, html_object):
s = smtplib.SMTP('server.com')
msg = MIMEMultipart()
msg.attach(MIMEText(body))
part = MIMEBase('text', "html")
part.set_payload(html_object)
part.add_header('Content-Disposition', 'attachment; filename="tbl.html"')
msg.attach(part)
sender = 'me#place.com'
msg['From'] = sender
msg['To'] = ", ".join(recipients)
msg['Subject'] = "Html Test"
s.sendmail(sender, recipients, msg.as_string())
print(f"Mail Sent to {sender}")
e.g.
mail('See attached for html file.',["me#place.com"],key="", html_object=df.to_html())
