What it is
In Python, packages and dependencies are installed globally by default, which can lead to conflicts between different projects that require different versions of the same package.
To avoid this, Python provides a way to create virtual environments, which are isolated environments that can have their own packages and dependencies, separate from the global Python installation.
For me, the best way to create virtual environments is through tools like uv, which simplify the process of creating and managing virtual environments, as well as handling dependencies and package management.
TIP
Always use virtual environments for Python projects. This prevents dependency conflicts and ensures reproducible builds across different machines.
