&& -> is used to join and run 2 commands in terminal
together at once

$ cd ~/python-environments
Enter fullscreen mode Exit fullscreen mode
  • Now create python virtual environment : 
$ virtualenv --python=python3.8 env_python38
Enter fullscreen mode Exit fullscreen mode

After running create virtual enviornment commant output in terminal would be like this :
