Multi-line 'Body' in mime email

Question

New to using mime within a python email... https://www.smallsurething.com/multi-line-strings-in-python/ : this guy provides a couple of ways to create a multi-line string, but I can't seem to convince mime to use it in the body of an email. body = """first line second line final line""" print(body) first line second line final line‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ # I use it in mime like this: msg = MIMEMultipart() msg["From"] = emailfrom msg["To"] = COMMASPACE.join(emailto) msg["Subject"] = "Please see attached xls for errors" body = """OriginObjectID & DestinationObjectID are the two lines in the error RuleDescription is what rule has been broken Name should be self-explanatory""" msg.attach(MIMEText(body,'plain'))‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ As shown in lines 6-8, this approach produces an indent that I'd like to avoid. template = ("This is the first line. " "This is the second line. " "This is the third line.") print(template) This is the first line. This is the second line. This is the third line.‍‍‍‍‍‍‍‍‍ msg = MIMEMultipart() msg["From"] = emailfrom msg["To"] = COMMASPACE.join(emailto) msg["Subject"] = "Please see attached xls for errors" body = ("OriginObjectID & DestinationObjectID are the two lines in the error " "RuleDescription is what rule has been broken " "Name should be self-explanatory") ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Is what I'd like to use, and it works great from the command line but when I use it mime, the newlines are ignored so the body of my email is one long run-on sentence. What's the secret to get a nice looking, multi line mime-email body?

explore textwrap a bit more... dedent, indent, wrap are a few of the gems that it contains. there are others

I imported the textwrap module as described here textwrap – Formatting text paragraphs - Python Module of the Week and tweaked my 'body' variable a little bit: import datetime,smtplib,textwrap,arcpy body = """ OriginObjectID & DestinationObjectID are the two lines in the error RuleDescription is what rule has been broken Name should be self-explanatory""" body = textwrap.dedent(body).strip() msg.attach(MIMEText(body,'plain')) ‍‍‍‍‍‍‍‍ and the email body looks like this: and that works for me!
