I have some code that generates a time-stamp as follows:
from datetime import datetime
tt = datetime.now()
timestamp = "%4d-%02d-%02d %02d:%02d" % \

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

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

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:

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.

That's a very good way of creating hard-to-read code and introducing

BeautifulSoup instead.
