I have a visz and a visc file format for my viscosity vpn profile. I would just like to know what is the syntax in order to convert the visz and visc file so I can use it on my OpenVPN client?

Do I save this script with extension .py?
How Do I then point my visc/visz file to convert it to an OpenVPN file format.

FYI: In Ubuntu, to install click, you cannot use pip3. Use the following to install click:

sudo apt install python-pip
pip install click

Then you'll be able to run the script above :)
