Hi guys, i'm new with python.. Actually, i'm trying to send featured email with python: html body, text alternative body, and attachment.

So, i've found this tutorial and adapted it with the gmail authentication (tutorial found here)

The code i have atm, is that:

def createhtmlmail (html, text, subject):

"""Create a mime-message that will render HTML in popular
  MUAs, text in better ones"""
import MimeWriter

import mimetools
import cStringIO
from email.MIMEMultipart import MIMEMultipart

from email.MIMEBase import MIMEBase

from email.MIMEText import MIMEText

from email.Utils import COMMASPACE, formatdate

from email import Encoders
import os


out = cStringIO.StringIO() # output buffer for our message 

htmlin = cStringIO.StringIO(html)

txtin = cStringIO.StringIO(text)


writer = MimeWriter.MimeWriter(out)

#
# set up some basic headers... we put subject here
# because smtplib.sendmail expects it to be in the

# message body
#
writer.addheader("Subject", subject)

writer.addheader("MIME-Version", "1.0")

#
# start the multipart section of the message
# multipart/alternative seems to work better

# on some MUAs than multipart/mixed
#
writer.startmultipartbody("alternative")

writer.flushheaders()
#
# the plain text section

#
subpart = writer.nextpart()

subpart.addheader("Content-Transfer-Encoding", "quoted-printable")

pout = subpart.startbody("text/plain", [("charset", 'us-ascii')])

mimetools.encode(txtin, pout, 'quoted-printable')

txtin.close()
#
# start the html subpart of the message

#
subpart = writer.nextpart()

subpart.addheader("Content-Transfer-Encoding", "quoted-printable")

#
# returns us a file-ish object we can write to
#
pout = subpart.startbody("text/html", [("charset", 'us-ascii')])

mimetools.encode(htmlin, pout, 'quoted-printable')

htmlin.close()


#
# Now that we're done, close our writer and

# return the message body
#
writer.lastpart()

msg = out.getvalue()
out.close()

return msg

import smtplib
f = open("/path/to/html/version.html", 'r')

html = f.read()
f.close()

f = open("/path/to/txt/version.txt", 'r')

text = f.read()
subject = "Prova email html da python, con allegato!"

message = createhtmlmail(html, text, subject)

gmail_user = "thegmailaccount@gmail.com"
gmail_pwd = "thegmailpassword"

server = smtplib.SMTP("smtp.gmail.com", 587)

server.ehlo()
server.starttls()

server.ehlo()
server.login(gmail_user, gmail_pwd)

server.sendmail(gmail_user, "example@example.com", message)

server.close()

and that works.. now only miss the attachment.. And i am not able to add the attachment (from this post)

So, why there is not a python class like phpMailer for php? Is it because, for a medium-able python programmer sending a html email with attachment and alt text body is so easy that a class is not needed? Or is because i just didn't find it?

If i'll be able to wrote a class like that, when i'll be enough good with python, would that be useful for someone?

Referring on this question, i have a similar -but not the same- problem..

On my way, i'll have some text file, structured like:

var_a: 'home'
var_b: 'car'

var_c: 15.5

And i need that python read the file and then create a variable named var_a with value 'home', and so on.

Example:

#python stuff over here
getVarFromFile(filename) #this is the function that im lookin for

print var_b
#output: car, as string
print var_c
#output 15.5, as number.

Is this possible, i mean, even keep the var type?

Notice that i have the full freedom to the text file structure, i can use the format i like if the one i proposed isn't the best.

EDIT: the ConfigParser can be a solution, but i dont like it so much, becose in my script i'll have then to refer to the variables in the file with

config.get("set", "var_name")

But what i'll love is to refer to the variable direclty, as i declared it in the python script..

There is a way to impoer the file as a python dictionary?

Oh, last thing, keep in mind that i dont know exactly how many variables would i have in the text file

Edit 2: i'm very interessing to the stephan json solution, becose in that way the text file could be readed simply with others languages (php, then via ajax javascript, for example), but i fail in something while acting that solution:

#for the example, i dont load the file but create a var with the supposed file content
file_content = "'var_a': 4, 'var_b': 'a string'"

mydict = dict(file_content)
#Error: ValueError: dictionary update sequence element #0 has length 1; 2 is required

file_content_2 = "{'var_a': 4, 'var_b': 'a string'}"
mydict_2 = dict(json.dump(file_content_2, True))

#Error:
#Traceback (most recent call last):
#File "<pyshell#5>", line 1, in <module>

#mydict_2 = dict(json.dump(file_content_2, True))
#File "C:\Python26\lib\json\__init__.py", line 181, in dump

#fp.write(chunk)
#AttributeError: 'bool' object has no attribute 'write'

In what kind of issues can i fall with the Json format? And, how can i read a json array in a text file, and transform it in a python dict?

p.s: i dont like the solution using .py files, i'll prefer .txt, .inc, .whatever is not restrictive to one language
