Test that the installation worked:
sh
   streamlit hello
Streamlit's Hello app should appear in a new tab in your web browser!
Use your new environment
Any time you want to use the new environment, you first need to go to your project folder (where the Pipenv file lives) and run:
sh
   pipenv shell
Now you can use Python and Streamlit as usual:
sh
   streamlit run myfile.py
When you're done using this environment, just type exit or press ctrl-D to return to your normall shell.
