What are the differences between venv and virtualenv?

Both venv and virtualenv are tools for creating isolated Python environments, but they have some differences. venv is included in the Python standard library starting from Python 3.3, while virtualenv is a third-party package that works with both Python 2 and 3. Additionally, virtualenv offers more features and flexibility, such as the ability to create environments with different Python versions.

Which one should I use for my project?

If you're using Python 3.3 or later and need a simple solution, venv is a great choice since it's built-in. However, if you need more features or are working with Python 2, virtualenv might be better.

Can I use both in the same project?

It's not recommended to use both in the same project as they can conflict with each other. It's best to stick with one tool for consistency.

What are some common commands for each?

For venv, you can create an environment with python -m venv myenv and activate it with source myenv/bin/activate. For virtualenv, you create it with virtualenv myenv and activate it similarly.
