Python and operating systems: a journey from novice to master

• The operating system is an intermediary that manages computer hardware and software resources.
• Master operating system concepts such as processes, threads, memory management, and I/O operations.

Python system module

• Explore python's os module, which provides an interface to operating system functionality.
• Use the os module to perform tasks such as file processing, process management, and environment variable interaction.

Process Management

• Understand the concept and life cycle of processes.
• Use os.fork() and os.exec() to create and manage processes.
• Control process behavior through signal processing.

Thread

• Understand the difference between threads and processes.
• Use the threading module to create and manage threads.
• Use threads to execute tasks in parallel to improve performance.

File system interaction

• Learn Python File processing libraries such as os.path and shutil.
• Create, read, write and manage files and directories.
• Understand file permissions and I/O operations.

System Programming

• Explore Python's ctypes module, which allows interaction with C libraries.
• Use ctypes to extend Python's functionality and interact with the underlying operating system.
• Write low-level system programs, such as device drivers or networkingtools.

Advanced Theme

• System monitoring: Use psutil or the resource module Monitor system resources such as CPU usage, memory, and network activity.
• Process Scheduling: Understand the process scheduling algorithm, and use the os.sched module to control process priority.
• Network Programming: Use Python's Socket module for network communication and implementation of server and client applications.
• Secure Programming: Apply Security practices such as user authentication, data encryption, and permissions management.

Master advanced skills

• Practice using Python system modules for real projects.
• Study operating system documentation and other resources to deepen your understanding.
• Take online courses or workshops to improve your skills.
• Collaborate with other developers to learn best practices and solve complex problems.

Become a Master

• In-depth understanding of the internal principles of the operating system.
• Be familiar with the features of different operating systems, such as windows, linux and MacOS.
• Master the systemProgramming languages, such as C or Rust, for high-performance and low-level tasks.
• Become an expert in automation, cloud computing and systems management.
