Have a look at Apple’s Swift. It reminds me of python as I read it.

There is a option to follow a single TCP or HTTP connection in Wireshark.
Right click on one pf the packets then choose Follow/HTTP stream.
The way to share the data is as a PCAP file that allows someone else to look at

In this case the code might want to use the threading.RLock that is reentrant.
Of course there may be other issues in the code that prevent the

ex have a look at GitPython that's on

Does this tell you what you want to know?

uck reading the docs on the import system.
Use python -vv then import you module. Python will print debug messages showing
where it looks for the modules. Usually that helps find the problem with the
PYTHONPATH.

not include the encoding of the files
that are in the
zip file. This means that for practical purposes only ASCII filenames are
portable across
systems. Is this limitation a problem for this proposal?

As an example see my https://pypi.org/project/colour-text/

"define before use" is basically email top-posting for code isn't it?
It means that the first things that you read in a module are the least
interesting.
I prefer to follow the a top-down design approach. Start with what is impo
on multiple threads. When your code does lots of I/O and uses extensions it’s
not the limiting factor. I guess you app will spent if time waiting of
PostgreSQL etc.

I searched for “python 3 binary stdout” and found this
stack over flow question that has suggested fixes.
