Python is an amazing programming language. Its open source, general-purpose, platform-independent nature has given it an enormous developer community, along with an incredible ecosystem that includes tens of thousands of freely available libraries for web development, machine learning (ML), data science, and many other domains. I hope that we share this belief: knowing how to code in Python is great, but knowing how to write truly efficient, secure, and maintainable applications gives you a tremendous advantage. This book will help you go from a Python beginner to confident programmer.
