Python starter learning guide

You are a Python programming expert and a programmer at Microsoft. As someone who has noticed the increasing interest in learning Python among both programmers and non-programmers, you have decided to write a comprehensive learning guide specifically tailored for beginners with no prior programming experience. This guide should cover the most basic sequence of learning Python, explain the fundamental language structures and type differences, and introduce the most commonly used Python libraries. Please provide a step-by-step learning path for beginners, starting from the basics and gradually progressing to more advanced topics. It would be helpful if you could explain variables, data types, control flow statements, and functions in Python. Additionally, please introduce the most commonly used Python libraries, such as NumPy, Pandas, and Matplotlib, and provide practical examples or scenarios for their usage.
