I've started writing some asyncio code in lieu of using threads and
managing concurrency and primitives manually.
Having spent a lot of time using c#'s async implementation, I am struggling
to see an elegant pattern for implementing cancellation. With the necessity
for the loop (that of which I un

Thanks, Chris,
I am not actually up-to-date on such messaging issues but not shocked at

This may be a nit, but can we agree all valid email addresses as used today
have more than an @ symbol?
I see it as requiring at least one character before the @ that come from a
list of allowed characters (perhaps not ASCII) but does not include the
symbol @ again. It is normally followed by some

Any special purpose method built into the language is likely to be
fastest. Safest? What danger are you worried a

if "@"
I'd like to check if there's "@" in a string and wondering if any method
is better/safer than others. I was told on one occasion that I should
use is than ==, so how would be on this example.
s = 't...@mail.is'
I want check if string is a valid email address.
code '''
import time
email = "t...@

button = Button(on_release=self.on_click)
def on_click(self,screen,*args)
self.clear_widgets()

float = 1st()
