Leveraging Editable Mode for Local Package Development in Python using Pip

In Python's package management ecosystem, Pip boasts the '-e' (or '--editable') option for specific scenarios. When would this option be advantageous to employ?

The answer lies in the implementation of editable mode, as detailed in the official documentation: "Installs a project in editable mode (i.e. setuptools "develop mode") from a local project path or a VCS url."

Essentially, when you install a package in editable mode, it links the package to its original location. This means that if you update the source files for that package, those changes will immediately reflect in your environment.

This proves immensely useful when actively developing a package on your system. Instead of manually updating the package in your virtual environment upon every code modification, editable mode provides a seamless integration, allowing you to iterate rapidly and test changes without hassle.

To illustrate, you can run the command 'pip install -e .' within the directory of your package to install it in editable mode. Alternatively, if your package resides elsewhere, use the full path to the 'setup.py' file, as in 'pip install -e ~/path/to/setup.py'.

By leveraging editable mode with Pip, you streamline the development process of local packages, empowering you to iterate swiftly and effectively.
