Adding a Local Dependency with Pip

Adding a local dependency in Python projects can be easily done using pip, the package installer for Python. This method is particularly useful when you are developing a library and an application simultaneously and want to test changes in real-time.

Steps to Add Local Dependency

1. Navigate to Your Project Directory: Open a terminal and navigate to the directory of the project where you want to add the local dependency.

2. Use Pip to Add Local Dependency:
   Run the following command, replacing path/to/local/library with the relative or absolute path to your local library directory.

   pip install -e path/to/local/library
   

3. Editable Mode:
   The -e flag installs the package in "editable" mode. Any changes made to the local library will be immediately available in the project that added it as a dependency.

Benefits

• Real-Time Testing: Instantly test how changes in your library affect applications that depend on it.
• Ease of Development: Simplify the development process when working on interconnected Python projects.
• No Need for Reinstallation: Avoid the need to reinstall the library after every change.
