pip install as editable

pip install -e is a powerful command that allows you to install a Python package in "editable" mode. This means that instead of copying the package files to the site-packages directory, a link to the package's source directory is created. This is particularly useful during development when you want to make changes to a package and see the effects without reinstalling it.
In this tutorial, we'll explore how to use pip install -e with code examples to help you get started.
Before you begin, ensure that you have Python and pip installed on your system. You can check their versions by running the following commands:
Now, create a module inside the package directory:
The dot (.) at the end indicates the current directory. This command creates a link to the source files rather than copying them.
Now that your package is installed in editable mode, you can use it in your Python scripts or interpreter.
Run the script:
You should see the output: "Hello, John!"
Since the package is installed in editable mode, any changes you make to the source files are immediately reflected without the need to reinstall.
In this tutorial, you learned how to use pip install -e for editable installations, enabling you to develop and make changes to a Python package without the need for constant reinstallation. This is a valuable tool for efficient development and testing workflows.
