You could construct a mailto URI

https://en.wikipedia.org/wiki/Mailto

>>> body = 'This is the text'
>>> to = 'god at heaven.example.com'
>>> cc = 'friedrich.nietzsche at unibas.ch'
>> mailto_url = urllib.parse.quote(f'mailto:{to}?') +
urllib.parse.urlencode({'cc': cc, 'subject': subject, 'body': body},
quote_via=urllib.parse.quote)

If you open that URI with the webbrowser module, it should work. Well,
it might. On my system, Chrome refuses to open a mailto URI like this,
but Firefox plays along.

The better option would be to call the mail program directly (such as
using the subprocess module), but how you find out what to call will
depend on your OS. If this is just for one PC and you use Thunderbird,
then you might as well hard-code the Thunderbird executable, of course...
