On the contrary, there are many programs than never use any path
operations. I have many programs which take input and provide output and
no files are involved at a

You'd get the same result with:

So, I _think_ what you are proposing is that there be a method something

Hi Michel,
Yes, theoretically, it's possible to try to change an event loop
policy while an event loop is running, but I've yet to see a library
(or user code) that tries to do that (it's pointless anyways). There
are libraries like uvloop that tell their users to explicitly install
a special poli
There are very few programs that never use any path operation.
Opening a file is such a common one we have a built-in for it with
open(), but you usually need to do some manipulation to get the file
path in the first place.
We have __file__, but the most common usage is to get the parent dir,

Maybe somebody already answered this, but what's the difference between
this and the keyword "assert", which basically can be stripped of using
"python -o" ?

After years of playing with asyncio, I'm still having a harder time
using it than any other async architecture around. There are a lot of
different reasons for it, but this mail want to address one particular one:
The event loop and policy can be tweaked at any time, by anyone.
Now, it's hard eno
Well that doesn't matter anyway. With breakpoint() we choose the
debugger implementation, so we could do the same here.
However, this would be addressing the wrong problem the problem is
verbosity. asyncio s are already aware of that, since they are working
on providing asycio.run() in 3.7.
Now t
i'd also be pretty simple to implement
Just list:
minute = timedelta(minutes=1)
hour = timedelta(hours=1)
etc...
and you could import and use them like that. Or if you really want to
write 5*m, the just from datetime import minute as m

second, minute, hour (singular) timedelta objects in the module are a good
idea, one could do 5 * minute to get a timedelta or one could do value /
minute to get a float.
a = datetime.now()
b = datetime(2018, 2, 3) + 5 * minute
print((a - b).total_seconds())
print((a - b) / minute)

I'm way out of my comfort zone now, but the parser could for
`123.45_f`
give
`__literal_f__(123.45)`
and then that function should be imported.
I'm sure this idea has many shortcomings that I don't see, but that was the
reason why
