Use a Virtual Environment to Manage Packages!

If you need a specific version of Python and to install Python packages, we recommend using a virtual environment.

Let's create the classic "Hello, World!" script. Create a file named hello.py with the following content:

hello.py

print("Hello, World!")

Open a Text Editor

Using JupyterHub: If you're logged into JupyterHub, you can create and edit this file using the built-in text editor.
Using the Command Line: If you're using the command line, you can create this file using vim hello.py or another text editor.
Terminal Input
```
vim hello.py
```

To execute the Python script, run the following command in the terminal:

Terminal Input

python3 hello.py

You should see the following output:

Terminal Output
