pip install editable

When developing Python projects, it's common to install dependencies to manage libraries and tools. The traditional way is to use pip install to install packages from PyPI. However, during development, you may want to make changes to a package and see the effects immediately without reinstalling it each time. This is where pip install -e (editable mode) becomes handy. This mode allows you to install a package in "editable" mode, meaning any changes you make to the source code are immediately reflected without reinstalling the package.
The . at the end indicates the current directory. This command installs the package in editable mode.
If you change the message in hello_world function to "Hello, Editable!", you can see the changes immediately without reinstalling:
You can run the code using Python and see the updated output:
Rapid Development: With editable installs, you can make changes to your code and test them without the need to reinstall the package each time.
Easy Collaboration: If you're working on a project with multiple developers, they can easily test and contribute changes without the need for frequent package installations.
Dependency Linking: If you're developing multiple projects simultaneously and one project depends on another, editable installs ensure that changes in the dependency are immediately reflected in the dependent project.
Using pip install -e is a powerful technique for development that allows you to streamline your workflow and see immediate results when making changes to your code. It's particularly useful when working on larger projects or collaborating with others, as it simplifies the process of testing and iterating on your code.
