venv is a tool in Python that allows users to create isolated environments for their projects. This means that each project can have its own dependencies, libraries, and Python versions without interfering with others. It helps prevent conflicts between packages and ensures that projects remain consistent and manageable. Using venv is straightforward. You can create a new virtual environment by running a simple command in your terminal. Once activated, any packages you install will only affect that specific environment, making it easier to maintain and share your projects without worrying about system-wide changes.
