Which URL do we need to type in our browser to launch JupyterLab if it does not start automatically?

To manually launch JupyterLab in your web browser, you typically need to type one of the following URLs in the address bar:

1. Default URL:

   http://localhost:8888/lab
   

2. Secure URL (if you have configured it to use HTTPS):

   https://localhost:8888/lab
   

Additional Information

• The term "localhost" refers to your local machine, indicating that JupyterLab is running on your computer.
• The number "8888" is the default port for JupyterLab. If you have set a different port in your Jupyter configuration, you'll need to replace "8888" with that port number.
• If JupyterLab was launched on a remote server, you'd replace "localhost" with the IP address or domain name of that server.

Make sure that JupyterLab is running before you attempt to access it by opening your terminal or command prompt and starting JupyterLab with the command:

jupyter lab
