Docker vs Virtualenv: Which Should I Use?

What's the difference between Docker and Virtualenv?

Docker is a containerization tool that packages applications and their dependencies, while Virtualenv is a tool for creating isolated Python environments.

When should I use Docker instead of Virtualenv?

Use Docker when you need to deploy applications across different environments or when you want to include system dependencies. Virtualenv is great for Python projects that need isolated environments.

Can I use Docker for Python projects?

Absolutely! Docker can be used to containerize Python applications, making them portable and easy to deploy.

Are there any performance differences between the two?

Docker can have a slight overhead due to containerization, but it often provides better resource management and scalability compared to Virtualenv.
