PYTHON: Sending email with an attachment that updates every 15 minutes

Below is a section of my code, it is in a while true loop to collect CO2 and Temperature readings from sensors every 15 minutes. It exports the data to a new CSV file every 15 minutes. The file name changes every 15 minutes as there is a date and time stamp required in the file name.
Can python be used to send an email with the CSV file attached if the file name is constantly changing?
I found the example below the dashed line online but the file location would be changing every 15 minutes in my case
for device in list_of_devices:
print (device)
for url_CO2 in list_of_urls_CO2:
headers = CaseInsensitiveDict()
headers['Accept'] = 'application/json'
headers['Authorization'] = bearer_token
resp_CO2 = requests.get(url_CO2, headers=headers)
response_CO2.append(resp_CO2.text)
print(resp_CO2.text)
for url_RT in list_of_urls_RT:
headers = CaseInsensitiveDict()
headers['Accept'] = 'application/json'
headers['Authorization'] = bearer_token
resp_RT = requests.get(url_RT, headers=headers)
response_RT.append(resp_RT.text)
print(resp_RT.text)
# importing pandas as pd
import pandas as pd
# dictionary of lists
myDict = {'Device': list_of_devices, 'CO2 Level': response_CO2, 'Room Temperature': response_RT}
df = pd.DataFrame(myDict)
# saving the dataframe
df.to_csv('test_{}.csv'.format(datetime.now().strftime("%Y-%m-%d %H.%M.%S")), index=False)

If you don't need to keep your files after send, it's easy to do like this:
Put your sending email code into the function named send_by_email for example
Then just collect all the files in the target dir, filter only csv-s and send them one by one (don't forget to delete file after send not to get into eternal loop on next iteration)
import os
mypath = '/tmp' # define path to dir with your files
filenames = next(os.walk(mypath), (None, None, []))[2] # list all files
csvs = [f for f in filenames if f.endswith('.csv')] # fileter only .scv files
for filename in csvs:
file_with_path = os.path.join(mypath, filename)
send_by_email(file_with_path)
os.remove(file_with_path)
If you need to keep files, you can just move them into another dir instead of deleting.

How can I attach the helloword.txt file in this email? This code is working fine, I just want to send an attachment along with it. This code lets me me send the body without any attachment. Also, how do I encrypt the key.txt file which store email address and password, and to send email it it requires the password to be entered (diff pass)?

You need to use the 'MIMEMultipart' module to attach files.
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
mail = MIMEMultipart()
mail["Subject"] = sent_subject
mail["From"] = sent_from
mail["To"] = sent_to
mail.attach(MIMEText(sent_body,'html'))
ctype, encoding = mimetypes.guess_type(_file)
maintype, subtype = ctype.split('/', 1)
fp = open("/path/to/attachment/file.txt")
# If file mimetype is video/audio use respective email.mime module.
# Here assuming 'maintype' == 'text' we will use MIMEText
msg = MIMEText(fp.read(), _subtype=subtype)
fp.close()
filename = os.path.basename(_file)
msg.add_header('Content-Disposition', 'attachment', filename=filename)
mail.attach(msg)
server.sendmail(sent_from, sent_to, mail.as_string())

How to change actual location to temporary, add headers and remove space in csv file on Python Email table from MySQL?

I have a python code that run a MySQL query and send a email with csv attachment. I need to make following three changes. Can anybody please help me with this?
I need to change the actual location to a temporary location (I tired, it gaves me an error then I chnage it to the real location)
I have no headers on my result csv file. How do I add header on result csv?
It puts a empty raw between each raw, how do I remove that too.
Code -
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.base import MIMEBase
import mysql.connector
import csv
my_db = mysql.connector.connect(
host="localhost",
user="root",
passwd="admin",
database="simplymacstaging"
)
my_cursor = my_db.cursor()
my_cursor.execute("SELECT CONVERT(DateCreated, Date) 'Date', StoreName, ROUND(sum(TotalCost), 2) 'TotalCost' "
"FROM simplymacstaging.ajdustmenthistory WHERE ReasonCode = 'Negligence - Service' AND "
"CONVERT(DateCreated, Date) >= '2019-02-03' GROUP by StoreName, Date")
databases = my_cursor.fetchall()
fp = open('C:\#Emailproject/emailtest.csv', 'w')
attach_file = csv.writer(fp)
attach_file.writerows(databases)
fp.close()
# My email
fromaddr = "******************#gmail.com"
# EMAIL ADDRESS YOU SEND TO
toaddr = "**********#gmail.com"
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "Test Email Data" # SUBJECT OF THE EMAIL
body = "Hello, Please see the attched report for week. Thank you, ****"
msg.attach(MIMEText(body, 'plain'))
filename = "Test Email.csv" # NAME OF THE FILE WITH ITS EXTENSION
attachment = open("C:\#Emailproject/emailtest.csv", "rb") # PATH OF THE FILE
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, "***********") # YOUR PASSWORD
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()
sample result image -
Thank you so much

to avoid the empty rows try this
fp = open('C:\#Emailproject/emailtest.csv', 'w', newline='')
to add the header row
attach_file.writerow(["date", "address", "col3"])
attach_file.writerows(databases)

Send mail in Lotus Notes using python

i need help for send a mail in the Lotus Notes using python, appear that the win32com can do it, but i don't found any complete example or tutorial. My idea is a simple function like it:
from win32com.client import Dispatch
import smtplib
def SendMail(subject, text, user):
session = Dispatch('Lotus.NotesSession')
session.Initialize('???')
db = session.getDatabase("", "")
db.OpenMail();
Some suggestion? Thanks!

Below is some code that I have used for this purpose for several years:
from __future__ import division, print_function
import os, uuid
import itertools as it
from win32com.client import DispatchEx
import pywintypes # for exception
def send_mail(subject,body_text,sendto,copyto=None,blindcopyto=None,
attach=None):
session = DispatchEx('Lotus.NotesSession')
session.Initialize('your_password')
server_name = 'your/server'
db_name = 'your/database.nsf'
db = session.getDatabase(server_name, db_name)
if not db.IsOpen:
try:
db.Open()
except pywintypes.com_error:
print( 'could not open database: {}'.format(db_name) )
doc = db.CreateDocument()
doc.ReplaceItemValue("Form","Memo")
doc.ReplaceItemValue("Subject",subject)
# assign random uid because sometimes Lotus Notes tries to reuse the same one
uid = str(uuid.uuid4().hex)
doc.ReplaceItemValue('UNIVERSALID',uid)
# "SendTo" MUST be populated otherwise you get this error:
# 'No recipient list for Send operation'
doc.ReplaceItemValue("SendTo", sendto)
if copyto is not None:
doc.ReplaceItemValue("CopyTo", copyto)
if blindcopyto is not None:
doc.ReplaceItemValue("BlindCopyTo", blindcopyto)
# body
body = doc.CreateRichTextItem("Body")
body.AppendText(body_text)
# attachment
if attach is not None:
attachment = doc.CreateRichTextItem("Attachment")
for att in attach:
attachment.EmbedObject(1454, "", att, "Attachment")
# save in `Sent` view; default is False
doc.SaveMessageOnSend = True
doc.Send(False)
if __name__ == '__main__':
subject = "test subject"
body = "test body"
sendto = ['abc#def.com',]
files = ['/path/to/a/file.txt','/path/to/another/file.txt']
attachment = it.takewhile(lambda x: os.path.exists(x), files)
send_mail(subject, body, sendto, attach=attachment)

If your company is set up such a way that a host IP address and Port is sufficient to send an email, then use the following:
import smtplib
from email.mime.base import MIMEBase
from email import encoders
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
def emailReport(attach_path,file_name,From,to,cc=None):
msg = MIMEMultipart()
msg['Subject'] = file_name
msg['From'] = From
msg['To'] = ", ".join(to)
msg['CC'] = ", ".join(cc)
msg.attach(MIMEText("****Body of your email****\n"))
#For multiple attachments repeat/loop the following:
part = MIMEBase('application', "octet-stream")
part.set_payload(open(attach_path.format(file_name), "rb").read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment; filename=%s' % file_name)
msg.attach(part)
#Repeat stops here....
s = smtplib.SMTP(host='xxx.xxx.xx.x',port=xx) #Enter your IP and port here
s.sendmail(From,to+cc,msg.as_string())
s.quit()
to=['Person1#email.com', 'Person2#email.com']
cc=['Person3#email.com', 'Person4#email.com']
From='Your#email.com'
attach_path=r'C:\Users\Desktop\Temp'
file_name='Test.xlsx'
emailReport(attach_path,file_name,From,to,cc)

Email multiple recipients Python

I'm trying to email multiple recipients using the pyton script below. I've searched the forum for answers, but have not been able to implement any of them correctly. If anyone has a moment to review my script and spot/resolve the problem it would be greatly appreciated.
Here's my script, I gather my issue is in the 'sendmail' portion, but can't figure out how to fix it:
gmail_user = "sender#email.com"
gmail_pwd = "sender_password"
recipients = ['recipient1#email.com','recipient2#email.com']
def mail(to, subject, text, attach):
msg = MIMEMultipart()
msg['From'] = gmail_user
msg['To'] = ", ".join(recipients)
msg['Subject'] = subject
msg.attach(MIMEText(text))
part = MIMEBase('application', 'octet-stream')
part.set_payload(open(attach, 'rb').read())
Encoders.encode_base64(part)
part.add_header('Content-Disposition',
'attachment; filename="%s"' % os.path.basename(attach))
msg.attach(part)
mailServer = smtplib.SMTP("smtp.gmail.com", 587)
mailServer.ehlo()
mailServer.starttls()
mailServer.ehlo()
mailServer.login(gmail_user, gmail_pwd)
mailServer.sendmail(gmail_user, to, msg.as_string())
mailServer.close()
mail("recipient1#email.com, recipient2#email.com",
"Subject",
"Message",
"attchachment")
Any insight would be greatly appreciated.
Best,
Matt

It should be more like
mail(["recipient1#email.com", "recipient2#email.com"],
"Subject",
"Message",
"attchachment")
You already have a array of recipients declared,that too globally,You can use that without passing it as an argument to mail.

I wrote this bit of code to do exactly what you want. If you find a bug let me know (I've tested it and it works):
import email as em
import smtplib as smtp
import os
ENDPOINTS = {KEY: 'value#domain.com'}
class BoxWriter(object):
def __init__(self):
pass
def dispatch(self, files, box_target, additional_targets=None, email_subject=None, body='New figures'):
"""
Send an email to multiple recipients
:param files: list of files to send--requires full path
:param box_target: Relevant entry ENDPOINTS dict
:param additional_targets: other addresses to send the same email
:param email_subject: optional title for email
"""
destination = ENDPOINTS.get(box_target, None)
if destination is None:
raise Exception('Target folder on Box does not exist')
recipients = [destination]
if additional_targets is not None:
recipients.extend(additional_targets)
subject = 'Updating files'
if email_subject is not None:
subject = email_subject
message = em.MIMEMultipart.MIMEMultipart()
message['From'] = 'user#domain.com'
message['To'] = ', '.join(recipients)
message['Date'] = em.Utils.formatdate(localtime=True)
message['Subject'] = subject
message.attach(em.MIMEText.MIMEText(body + '\n' +'Contents: \n{0}'.format('\n'.join(files))))
for f in files:
base = em.MIMEBase.MIMEBase('application', "octet-stream")
base.set_payload(open(f, 'rb').read())
em.Encoders.encode_base64(base)
base.add_header('Content-Disposition', 'attachment; filename={0}'.format(os.path.basename(f)))
message.attach(base)
conn = smtp.SMTP('smtp.gmail.com', 587)
un = 'user#gmail.com'
pw = 'test1234'
conn.starttls()
conn.login(un, pw)
conn.sendmail('user#domain.com', recipients, message.as_string())
conn.close()

I was facing the same issue, I fixed this issue now. Here is my code -
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib
import datetime
def sendMail():
message = MIMEMultipart()
message["To"] = "xxxxx#xxxx.com,yyyy#yyyy.com"
message["Cc"] = "zzzzzz#gmail.com,*********#gmail.com"
message["From"] = "xxxxxxxx#gmail.com"
message["Password"] = "***************"
server = 'smtp.gmail.com:587'
try:
now = datetime.datetime.now()
message['Subject'] = "cxxdRL Table status (Super Important Message) - "+str(now)
server = smtplib.SMTP(server)
server.ehlo()
server.starttls()
server.login(message["From"], message["Password"])
server.sendmail(message["From"], message["To"].split(",") + message["Cc"].split(","), message.as_string())
server.quit()
print('Mail sent')
except:
print('Something went wrong...')
sendMail()
