How do I send this email in Python, opening files and stuff?

msg = EmailMessage(subject, body, from_email, [to_email])
msg.content_subtype = "html"
msg.send()

This is how I send an email in Django.

But what开发者_如何学Python if I want to open a text file and take into account all its line breaks and tabs. I want to take the body of the text file (with line breaks \n) and email it as text of the "body".

If it's a text file, just send it as text. If you send it as "HTML", the whitespace won't be significant.

In Django itself, it uses render_to_string("", {}) from django.template.loader. The advantage of it is that you can use contexts.
