That's a very good way of creating hard-to-read code and introducing
subtle bugs and unexpected behaviours. Try using an HTML parser like

Hello,
I'm trying to get my head around asyncio, and I think I'm mostly there
now, (but expect to be proved wrong :-)!). It appears to be about the
newest of the PEPs according to my searches, including PEP 0, so I don't
expect a huge amount of supporting documentation out there yet.

Hello community, this is my first email to this list. Sorry if this sounds
dumb, but anytime I do a google search I notice that the first result is
from Python 2 docs. I always have to remind my students about it, and
sometimes I even trip myself.

I was profiling a slow function in an application last week, and came
across something that I still can’t explain. Inside a loop that was being
called 4 times, inside a for loop that ran for a few dozen times there was
a list compression of the form:
[x.id for x in some_function()]

It is impossible to diagnose without seeing more context. Specifically,
you'll need to share the code around this line. The whole function,
preferably.

The function IMHO must be returning a generator. I would look for a problem
in the generator code.

The length of the list produced by the comprehension also give you good
information.

Hi everyone! I need help transferring an image via TCP from a python program on
my raspberry pi to an android application.
I have set up a client-server architecture such that my raspberry pi 3 records
audio, performs some analysis on it, and then sends the data (via TCP) to the
android app to

Assuming you're using Python 3, why not use an f-string?
>>> dt = datetime.datetime.now()
>>> dt.strftime("%Y-%m-%d %H:%M")
'2019-07-22 16:10'
>>> f"{dt:%Y-%m-%d %H:%M}"
'2019-07-22 16:10'

I no longer have one to verify, but I recall Solaris boxen used /bin/env
not /usr/bin/env.

We are using `#!/usr/bin/env python`, for example on

For bash we are using `#!/usr/bin/env bash`. I don't know if those are the
best but they work.

According to the profiler, some_function was being called 52,000 times
Is some_function recursive, by any chance?
