Let's ignore the facts that there is an existing mail library, that you
should use real parameters if they are required and that exit() is
completely
Just a few tricks you may have missed:

Wow, lots of things I had never heard of in your posts.
I guess I need to do some homework...

Hi,
I'm writing a small mail library for my own use, and at the time I'm
testing parameters like this:
class Mail(object):
def __init__(self, smtp, login, **params)
blah

required = ['Subject', 'From', 'To', 'msg']
for i in required:
if not i

A list evaluates as true if it is not empty. As long as at least one

assert[key for key in required if key in params.keys()]

Could you explain why it doesn't work and do you have any idea of how it
could work ?
Well, here, if any of the items are found, you get a list that is
non-False'ish, so the assert passes.
It sounds like you want all() (available as

Thanks everyone for your answers. That's much clearer now.
I see that I was somehow fighting python instead of using it. Lesson
learned (for the time being at least) :)
I'll probably get back with more questions...
