Python 与操作系统:从新手到大师的进阶之旅

  • 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.

How do you slice a Python array?How do you slice a Python array?May 01, 2025 am 12:18 AM

The basic syntax for Python list slicing is list[start:stop:step]. 1.start is the first element index included, 2.stop is the first element index excluded, and 3.step determines the step size between elements. Slices are not only used to extract data, but also to modify and invert lists.

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
