The answer is that they include extension modules, sometimes called native modules. But how can these packages do things that arenвЂ™t possible in regular Python? Like image processing with Pillow, high-performance machine learning with scikit-learn, or micro-threading with greenlet. One of the benefits of installing a separate package is the ability to do something that you couldnвЂ™t normally do вЂ“ in many cases, this is something that would be completely impossible otherwise. To explain why we need this tool, we need to look at a common pattern in Python packages. What is vcvarsall.bat, and why do I need it? What is this mythical batch file? Why do I need it? Where can I get it? How do I help Python find it? When will we be freed from this pain? LetвЂ™s look at some answers to these questions.
