Finally, I have compiled a Python learning roadmap and resource code, hoping to help friends who are learning Python break through information barriers and progress together:

A compilation of technical points in all directions of Python, forming a summary of knowledge points in various fields. Its usefulness lies in that you can find corresponding learning resources based on the knowledge points above, ensuring a comprehensive learning experience.

Essential Development Tools

After having a certain foundation and independent understanding ability, I will read books by predecessors or take handwritten notes. These materials detail their unique understanding of technical points, allowing me to learn different perspectives and broaden my horizons.

Watching learning videos during the zero-based stage is an efficient way to get started. Following the teacher’s thought process from the basics to deeper levels can easily help grasp the introductory knowledge.

Optical theory is far from enough; it is essential to practice coding hands-on. Only through practical case exercises can what has been learned be truly transformed into practical application skills.

How to obtain:

1. Follow the public account

2. Forward + reply with the keyword “materials” to get it
