Python virtual environment

I finally get to use python virtual environment using venv module to be created under ~/.venv/. (I wanted to upload a package to pypi.org)

 $ apt install python3-pip twine
 ...
 $ python3 -m venv ~/.venv
 $ source ~/.venv/bin/activate
(.venv) $ install --upgrade pip
 ...
(.venv) $ install --upgrade twine
 ...
(.venv) $ deactivate

System packages were current enough to cause printing Found existing installation: pip 23.0.1, etc. and no new packages were installed in ~/.venv.

Anyway, I now know how to activate and deactivate python virtual environment.

My motivation to use venv was to get the latest twine for pypi.org upload. It turned out that the system twine was new enough for pypi.org.

Helper

I added followings to my ~/.bashrc for the moment:

# create python venv @ $1
venv-create () {
  python3 -m venv $1
}

# activate python venv @ $1
venv-activate() {
  source $1/bin/activate
}

# update python venv
venv-update () {
  pip list --outdated |tail -n +3|cut -d ' ' -f 1|xargs -n1 pip install -U
}

Let me see if they are useful.
