Bite Code @bitecode@framapiaf.org

I was hoping for iter and callable to be part of the ride, as this is going to lead people to use list/tuple instead of typing.Iterable since it's easier to type.

But it's a nice improvement.

Now if PEP 604 is added into the mix, 3.9 will start to look seriously sexy

PEP 585 has been merged into #python 3.9 https://github.com/python/cpython/pull/18239

This is a huge step toward making type hints accessible as it allows to do:

dict[tuple[int, int], list[str]]

Instead of:

from typing import Dict, List, Tuple
Dict[Tuple[int, int], List[str]]

On of the reason I'm still using pew is because it let you create a venv without a project, yet associate a project dir with a venv later with auto cd.

It's possible dephell will implement this at some point. Finger crosses.

Tired of typing those two lines:

cd github/project
conda activate project

I added an activate function to my .bashrc

activate project

A New Way of Playing Japanese and English Games Side-By-Side « Legends of Localization https://legendsoflocalization.com/a-new-way-of-playing-japanese-and-english-games-side-by-side/

Oh, one last thing: you can't use it as a context manager :(

So pexpect is way more confortable, but you don't always want another dependancy.

asyncio.subprocess works on Unix and Windows, but
is available for Windows only if a ProactorEventLoop is used (it's now the default in python 3.8)

It has a few gotchas though:

- failing to pass a byte count to http://proc.stdout.read() will likely block forever
- proc.stdin.write() accepts only bytes, no str
- last print needs flush=True or you'll get a warning
- you have to process it all manually

print(await http://proc.stdout.read(64))
proc.stdin.write(b"a\n")
print(await http://proc.stdout.read(64))
proc.stdin.write(b"b\n")
print(await http://proc.stdout.read(64), flush=True)

And that's it, I started the process and answered the questions!

Inside my main() function, I can start the subprocess:

proc = await aio.create_subprocess_exec(
"sh", "http://test.sh", stdin=PIPE, stdout=PIPE,
)

And then communicate with it:

import asyncio as aio

PIPE = aio.subprocess.PIPE

async def main():
....

http://aio.run(main())

echo -n "Foo: "
read foo
echo -n "Bar: "
read bar
echo "You chose $foo and $bar"

I want to pilot it to do:

Foo: a
Bar: b
You chose a and b

Then I can do:

Using the "asyncio.subprocess" module, you can communicate back and forth with subprocesses, unlike the subprocess module which is a one time blocking deal. No need for pexpect!

It's very handy for tests and automation.

Let's say I have this bash script:
