Are you tired of manually executing your Python scripts every time you install them with Distutils or Setuptools? If you’re looking to automate this task and make your life easier, then look no further! Automating the execution of Python scripts after installation is a crucial step in streamlining your development process. In this article, we’ll dive into the various ways you can automate the process using different techniques and tools.To start, we’ll explore how to use entry points in setup.py to specify which script should be executed after installation. We’ll also discuss how to create batch files for Windows users and shell scripts for Unix-like systems like Linux and macOS. Additionally, we’ll cover how to package your Python scripts as standalone executables using PyInstaller or cx_Freeze, providing a way to distribute and run your applications without requiring the installation of Python on the target system.By the end of this article, you’ll have a better understanding of how to automate the execution of your Python scripts after installation, saving you valuable time and effort. Whether you’re a seasoned developer or just starting with Python, automation is a critical skill to have in your toolkit. So, what are you waiting for? Let’s dive in and start automating today!
“Execute A Python Script Post Install Using Distutils / Setuptools” ~ bbaz
Introduction
Python is a popular programming language that helps automate repetitive tasks. It has a vast number of libraries & tools available that assist developers in building efficient applications. One of the essential tasks while working on python projects is to automate python script execution. In this article, we will discuss two such methods to accomplish this task- with Distutils and Setuptools.
Distutils
Distutils is the built-in module in the Python standard library that facilitates the distribution of Python modules. It allows you to create, install and distribute Python packages. With distutils, you can add your Python script to the system path so that it can be executed from anywhere on the command line.
Installing Python Modules with Distutils
To install a python module, you can execute the following command:
“`python setup.py install“`
Distributing your Python Application with Distutils
To distribute your python application, you need to create a setup.py file that includes the metadata for your package. It contains information about your package like name, version, author, etc. Once you’ve included this information in the setup.py file, you can create a distribution package by running:
“`python setup.py sdist“`
Setuptools
Setuptools is a third-party library that simplifies package development and distribution. It is built on top of distutils and provides additional features like dependency management and easy plugin discovery. The setuptools package provides the setup() function that enables developers to create a distribution package.
Installing Python Modules with Setuptools
Setuptools include the functionality to manage dependencies for packages. It can automatically download any missing packages before installation. To install a python module using setuptools, you can execute the following command:
“`python setup.py develop“`
Distributing your Python Application with Setuptools
Setuptools can create distribution packages in various formats like source distributions, binary distributions, etc. The setup.cfg file contains information like package name, version, author, etc. Once you’ve included this information in the setup.cfg file, you can create a distribution package using the following commands:
“`python setup.py sdistpython setup.py bdist_wheel“`
Comparison Table
| Criteria | Distutils | Setuptools |
|---|---|---|
| Dependency Management | No | Yes |
| Plugin Discovery | No | Yes |
| Metadata Management | Less | More |
| Package Distribution Formats | Simple Formats | Multiple Formats |
Opinion
Both methods have their advantages and disadvantages. Distutils is the default Python module for packaging and distributing Python packages. Still, it doesn’t offer dependency management or plugin discovery features like Setuptools.
Setuptools enhances distutils and offers more features that can be beneficial during the development cycle. It includes tools for automatic package discovery, dependency management, and metadata inclusion of packages.
In conclusion, Setuptools provides more advanced packaging features that make the distribution of your python applications more comfortable. However, if you don’t need these additional features, Distutils can fit your needs for simple python package distribution.
Thank you for taking the time to read through our blog about automating Python script execution after installation with Distutils/Setuptools. We hope that you found the information provided helpful and informative.
As you may have learned, using Distutils or Setuptools can significantly streamline the process of distributing and installing Python packages and modules. By leveraging these powerful tools, you can easily automate the installation process and ensure that your script is executed as soon as it’s installed, without any manual intervention required.
If you’re interested in incorporating these techniques into your own Python development process, we encourage you to dig deeper into the topics we’ve covered here. In addition to the resources provided in this blog post, there are many excellent online tutorials and guides that can help you get started with Distutils and Setuptools.

People also ask about Automate Python script execution after installation with Distutils/Setuptools:
- What are Distutils and Setuptools?
- How do I use Distutils/Setuptools to install my Python script?
- Can I automate the execution of my Python script after installation?
Distutils and Setuptools are libraries in Python that allow developers to package and distribute their Python code. Distutils is included in the standard Python library, while Setuptools is a third-party library that provides additional functionality.
To use Distutils or Setuptools to install your Python script, you need to create a setup.py file that contains information about your script, such as its name, version, and dependencies. You can then run the setup.py file using the command python setup.py install. This will install your script on the user’s system.
Yes, you can use the entry_points feature in Setuptools to automate the execution of your Python script after installation. In your setup.py file, you can define an entry point for your script, specifying the script’s name and the function that should be executed when the script is run. For example:
- entry_points = {‘console_scripts’: [‘my_script=my_package.my_module:main’]}
This will create a command called my_script that will execute the main function in the my_module module of the my_package package when it is run.
To uninstall your Python script that was installed with Distutils or Setuptools, you can use the command pip uninstall [package_name]. This will remove the package and all its files from the user’s system.
