VirtualPython

virtualpython gives simple wrappers around the regularly used python tools pythonand pip to allow them to automatically understand that they are inside of a virtual environment directory, and then behave as if that virtual environment has been activated without the hassle of activating and deactivating it.

source ./venv/bin/activate
pip install -r requirements.txt
python my_python_code.py
deactivate

becomes

vpip install -r requirements.txt
vpython my_python_code.py

Additionally if you want to run an executable downloaded inside of the virtual environment you can execute it with

vbin someexecutable --with some --args
