I am going through some old code that I have written. This particular package, published on PyPI uses the ‘scrapy’ Python package to scrape a website for images.
The setup configuration can be viewed inside the ‘setup.py’ file. This file is generally added to a Python project to make it a package easily available for installation via some tool like, ‘pip’ and via some website like, ‘pipy.org’. The ‘setup.py’ file makes it.easy to mention the dependencies, which can be automatically installed by the package installer. This ‘imagebot’ package depends on a few external Python packages, like, ‘scrapy’, a Python scraping package, ‘PIL/Pillow’, a Python image processing library and ‘mutils’, a Python library written by me to include commonly used Python code. I think, that, this ‘setup.py’ is the file executed first by a package installer. One can mentioned metadata, like, author, version, categories, email, description, etc. in this file. One can also include additional code execution in this file, the code necessary to be executed at the installation time fits this kind of inclusion.
