Python installs modules system wide. This is unlike other programming languages where you need to import modules.
System wide installs of modules can create conflicts, you want virtual environments.
on Ubuntu Linux
Setup virtual environment
On Ubuntu 18.x:
sudo apt-get install python3-venv
On other systems, you need another command to install. It's highly likely its installed by default on Mac and Windows.
Create Virtual Environment
Create Virtual Environment in the command line.
To create a new virtual environment:
python3.6 -m venv test
or
pyvenv test
Activate Virtual Environment
After creation, you need to activate virtual environment.
To activate the virutal environment
cd venv
source bin/activate
Then modules are only installed in the virtual environment, not conflicting with other python programs.
