Today I will introduce 20 Python libraries for commonly used tools. I believe you will feel that you can't live without them after reading them.

They are: (Recommended learning: Python video tutorial)
Requests.Written by Kenneth Reitz The most famous http library. Every Python programmer should have it.
Scrapy. If you are engaged in crawler-related work, then this library is also essential. After using it, you won't want to use other similar libraries again.
wxPython. A GUI (graphical user interface) tool for Python. I mainly use it as a replacement for tkinter. You will love it.
Pillow. It is a friendly fork of PIL (Python graphics library). More user-friendly than PIL, it is a must-have library for anyone working in the graphics field.
SQLAlchemy. A database library. It received mixed reviews. The decision whether to use it or not is up to you.
BeautifulSoup. I know it is slow, but this xml and html parsing library is very useful for newbies.
Twisted. The most important tool for web application developers. It has a very beautiful API and is used by many Python development experts.
NumPy. How could we lack such an important library? It provides many advanced mathematical methods for Python.
SciPy. Since we mentioned NumPy, we have to mention SciPy. This is a Python algorithm and mathematical tool library. Its functions attract many scientists from Ruby to Python.
matplotlib. A library for drawing data graphs. Very useful for data scientists or analysts.
Pygame. Which programmer doesn’t like playing games and writing games? This library will make you even more powerful when developing 2D games.
Pyglet. 3D animation and game development engine. The very famous Python version of Minecraft is made using this engine.
pyQT.Python GUI tool. This is my second choice after wxPython when developing user interfaces for Python scripts.
pyGtk. is also a Python GUI library. The famous Bittorrent client is made of it.
Scapy. Packet detection and analysis library written in Python.
pywin32. A Python library that provides methods and classes for interacting with windows.
nltk. Natural language toolkit. I know most people won't use it, but it's very versatile. It's a great library if you need to handle strings. But its function is much more than that, explore it yourself.
nose.Python testing framework. Used by thousands of Python programmers. If you do test-oriented development, it's essential.
SymPy.SymPy can do algebraic evaluation, differentiation, expansion, complex numbers, etc. It is packaged in a pure Python distribution.
IPython. It’s hard to overstate the functionality of this tool. It takes Python's prompt information to the extreme. Including completion information, historical information, shell functions, and many other aspects. Be sure to research it.

Python vs. C : Learning Curves and Ease of UseApr 19, 2025 am 12:20 AMPython is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.
Python vs. C : Memory Management and ControlApr 19, 2025 am 12:17 AMPython and C have significant differences in memory management and control. 1. Python uses automatic memory management, based on reference counting and garbage collection, simplifying the work of programmers. 2.C requires manual management of memory, providing more control but increasing complexity and error risk. Which language to choose should be based on project requirements and team technology stack.
Python for Scientific Computing: A Detailed LookApr 19, 2025 am 12:15 AMPython's applications in scientific computing include data analysis, machine learning, numerical simulation and visualization. 1.Numpy provides efficient multi-dimensional arrays and mathematical functions. 2. SciPy extends Numpy functionality and provides optimization and linear algebra tools. 3. Pandas is used for data processing and analysis. 4.Matplotlib is used to generate various graphs and visual results.
Python and C : Finding the Right ToolApr 19, 2025 am 12:04 AMWhether to choose Python or C depends on project requirements: 1) Python is suitable for rapid development, data science, and scripting because of its concise syntax and rich libraries; 2) C is suitable for scenarios that require high performance and underlying control, such as system programming and game development, because of its compilation and manual memory management.
Python for Data Science and Machine LearningApr 19, 2025 am 12:02 AMPython is widely used in data science and machine learning, mainly relying on its simplicity and a powerful library ecosystem. 1) Pandas is used for data processing and analysis, 2) Numpy provides efficient numerical calculations, and 3) Scikit-learn is used for machine learning model construction and optimization, these libraries make Python an ideal tool for data science and machine learning.
Learning Python: Is 2 Hours of Daily Study Sufficient?Apr 18, 2025 am 12:22 AMIs it enough to learn Python for two hours a day? It depends on your goals and learning methods. 1) Develop a clear learning plan, 2) Select appropriate learning resources and methods, 3) Practice and review and consolidate hands-on practice and review and consolidate, and you can gradually master the basic knowledge and advanced functions of Python during this period.
Python for Web Development: Key ApplicationsApr 18, 2025 am 12:20 AMKey applications of Python in web development include the use of Django and Flask frameworks, API development, data analysis and visualization, machine learning and AI, and performance optimization. 1. Django and Flask framework: Django is suitable for rapid development of complex applications, and Flask is suitable for small or highly customized projects. 2. API development: Use Flask or DjangoRESTFramework to build RESTfulAPI. 3. Data analysis and visualization: Use Python to process data and display it through the web interface. 4. Machine Learning and AI: Python is used to build intelligent web applications. 5. Performance optimization: optimized through asynchronous programming, caching and code
Python vs. C : Exploring Performance and EfficiencyApr 18, 2025 am 12:20 AMPython is better than C in development efficiency, but C is higher in execution performance. 1. Python's concise syntax and rich libraries improve development efficiency. 2.C's compilation-type characteristics and hardware control improve execution performance. When making a choice, you need to weigh the development speed and execution efficiency based on project needs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
