Python Disposable Virtual Environment Using Venv Package

zshrc_et_al

function venvtemp {
    # Inspired by:  https://gist.github.com/csinchok/9714005#file-bash_profile
    THROWAWAY_DIR=$(mktemp -d -t venv);
    cd $THROWAWAY_DIR;
    python3 -m venv venv;
    source venv/bin/activate;

    printf "\n\nMaybe run:\n\tpython -m pip install --upgrade pip wheel setuptools\n\n"

    printf "Consider:\n\texport PIP_DEFAULT_TIMEOUT=100 && python -m pip install <PACKAGES> \\\t
 --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org\n\n"
}

Some different design choices from:
https://gist.github.com/csinchok/9714005#file-bash_profile

• Using venv package
• Not removing the environment (reboots should wipe them out)
• Adding some usage hints (specific to my needs... YMMV)

And actually, I figured why not use this for permanent virtualenvs by having it take an optional directory name (but still create on in a temp dir if param is not provided:

venvmake () {
	if [[ "$1" != "" ]]
	then
		local venv_dir=$1 
		mkdir "$venv_dir"
	else
		local venv_dir="$(mktemp -d -t venv)" 
	fi
	cd $venv_dir
	python3 -m venv venv
	source venv/bin/activate
	printf "\n\nMaybe run:\n\tpython -m pip install --upgrade pip wheel setuptools\n\n"
	printf "Consider:\n\texport PIP_DEFAULT_TIMEOUT=100 && python -m pip install <PACKAGES> \\\t  --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org\n\n"
}
