What is Python?

Python is a high-level, interpreted, general-purpose programming language developed by Guido van Rossum in the Netherlands in 1989 and officially released in 1991.

• With its concise syntax, ease of learning, and powerful functionality , Python has quickly become one of the world’s most popular programming languages, widely used in fields such as artificial intelligence (AI), data science, web development, and automation.

Key Features of Python

1. The syntax is concise and easy to understand
   • Python is designed with readability as its core principle, and its English-like syntax allows beginners to quickly get started.
   • For example, to print a line of text, only one line of code is needed:print("Hello, World!")
2. Cross-platform support
   • Python can run on multiple operating systems such as Windows, macOS, and Linux without modifying the source code.
3. Large Standard Library
   • Numerous built-in modules support file operations, network communications, mathematical operations, regular expressions, and other functions, saving development time.
4. Rich third-party packages
   • Through **PyPI（Python Package Index**, you can easily install a variety of packages, such as: NumPy(Numerical Computing), Pandas(Data Analysis), TensorFlow(Machine Learning), Flask(Web Development), etc.
5. Support multiple programming paradigms
   • It includes object-oriented (OOP), procedural, functional and other styles, with high flexibility.
6. Strong community support
   • There is a huge Python developer community around the world with rich resources and rapid updates, making it easy to find answers to problems.

Python’s main application areas

• Artificial Intelligence (AI) and Machine Learning
  • Develop intelligent systems and predictive models using tools such as TensorFlow, PyTorch, and Keras.
• Data Analytics & Big Data
  • Combine Pandas, NumPy, Matplotlib, Seaborn and other packages for data processing and visualization.
• Web Development
  • Use lightweight or full-featured frameworks such as Flask and Django to build websites and API services.
• Automation & Scripting
  • Improve efficiency by writing batch processing, web crawling, automated testing and other daily tasks.
• FinTech and Quantitative Trading
  • Develop trading robots, investment strategy simulations, and financial data analysis tools.
• Scientific Computing
  • Applied in scientific research in fields such as astronomy, bioinformatics, and physical simulation.
• Game Development
  • Make small games or prototypes using libraries like Pygame.

Python version development

• Python 2.x series
  • It was once the mainstream version, but support was officially stopped in early 2020.
• Python 3.x series (currently mainstream)
  • Improved syntax consistency and internationalization support make it the preferred version for all new projects today.

(🔔Reminder: It is recommended to learn and use Python 3 , as Python 2 is no longer updated.)

Summary of Python’s advantages

• The learning curve is gentle and suitable for beginners.
• The application areas are wide and almost all-encompassing.
• There are abundant community resources and teaching materials.
• It has high scalability and integration, and can be used with other languages ​​such as C and C++.
• In the era of AI and big data, the demand has skyrocketed, and it has strong employment competitiveness.
