 Congrats on completing the Python tutorial! During the course of this tutorial, you learned how to create a Python project, create a virtual environment, run and debug your Python code, and install Python packages. Explore additional resources to learn how to get the most out of Python in Visual Studio Code!
 
+## Managing dependencies across environments
+When working on Python projects, it’s essential to manage your dependencies effectively. One useful tip is to use the `pip freeze > requirements.txt` command. This command helps you create a `requirements.txt` file that lists all the packages installed in your virtual environment. This file can then be used to recreate the same environment elsewhere.
+
+Follow these steps to create a `requirements.txt` file:
+1. Activate your virtual environment, if you haven’t already.
+
+   ```bash
+   source venv/bin/activate  # On macOS/Linux
+   ```
+
+   ```powershell
+   .\venv\Scripts\activate   # On Windows
+   ```
+
+2. Generate the `requirements.txt` file.
+
+   ```powershell
+   pip freeze > requirements.txt
+   ```  
+
+3. You can now use the `requirements.txt` file to install dependencies in another environment.
+
+   ```powershell
+   pip install -r requirements.txt
+   ```
+
+By following these steps, you ensure that your project dependencies are consistent across different environments, making it easier to collaborate with others and deploy your project.
