What are the differences between Python virtual environments and Docker?

Python virtual environments (venv) are used to create isolated environments for Python projects, allowing you to manage dependencies separately. Docker, on the other hand, is a containerization platform that packages applications and their dependencies into containers, ensuring they run consistently across different environments.

When should I use a virtual environment instead of Docker?

You should use a virtual environment when you're working on a Python project that doesn't require complex dependencies or when you want a lightweight solution. Docker is more suitable for applications that need to run in different environments or when you want to ensure consistency across development, testing, and production.

Can I use both together?

Yes, you can use both together! You can create a virtual environment within a Docker container to manage Python dependencies while still benefiting from Docker's isolation and portability.

What are the advantages of using Docker over venv?

Docker provides greater isolation, allows you to package your application with all its dependencies, and ensures it runs the same way on any system. This is particularly useful for complex applications or microservices.
