# Running Python Interactively

To use the system Python software on the Yen servers, simply type `python3`.

Yen Terminal Input

```
python3
```

This Python can be found at `/usr/bin/python3`

Upon entering `python3`, you should see output similar to the following:

Yen Terminal Output

```
Python 3.10.12 (main, Sep 11 2024, 15:47:36) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
```

This will load the system Python version (Python 3.10.12)

To exit the Python interpreter, type `exit()` or press `Ctrl`+`D` .

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](/_user_guide/python_envs/#creating-a-new-virtual-environment-with-venv).

### Running Python Scripts

#### 1. Create a Python Script

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](/_getting_started/jupyter/#text-file-editor).

- **Using the Command Line**: If you're using the command line, you can create this file using [`vim hello.py`](/blog/2023/09/20/editing-files-on-the-command-line) or another text editor.

  Terminal Input

  ```
  vim hello.py
  ```

#### 2. Run the Python Script

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

```
Hello, World!
```
