Python virtualenv

When working with Python, it is generally so that work is done using virtual environments. Install virtualenvwrapper via pip install virtualenvwrapper --user

Add the following snippet to your ~/.bashrc file:

# install virtualenvwrapper using pip install virtualenvwrapper --user
if [ -f $HOME/.local/bin/virtualenvwrapper.sh ]; then
    # Locate the global Python where virtualenvwrapper is installed.
    if [ "$VIRTUALENVWRAPPER_PYTHON" = "" ]; then
        VIRTUALENVWRAPPER_PYTHON="$(command \which python3)"
    fi
    export WORKON_HOME=$HOME/.virtualenvs
    source $HOME/.local/bin/virtualenvwrapper.sh
fi

if [ -d $HOME/.pyenv ]; then
    export PYENV_ROOT="$HOME/.pyenv"
    export PATH="$PATH:$PYENV_ROOT/bin"
fi

You can now manage virtualenvs by running mkvirtualenv name to create a new virtualenv. Virtualenv then creates a few aliases. You can switch between environs with workon. Simply type deactivate as you would on a normal venv to exit back to your normal bash.
