Why use python for data analysis?
1. Python’s large number of libraries provide a complete toolset for data analysis (recommended learning: Python video tutorial)
2. Compared with MATLAB, R language and other languages that are mainly used for data analysis, the python language has more complete functions
3. The number of python libraries has been increasing , the method adopted to implement the algorithm is more innovative
4. Python can be easily connected to other languages, such as c, java, etc.
2 , What is IPython?
IPython is a python interactive shell (its default python shell is much easier to use and more powerful)
1. Supports automatic code completion and automatic Indentation, already supports bash shell
2, Jupyter NoteBook (formerly known as IPython NoteBook), which provides an interface for users to interact with the IPython kernel, and it is also an interactive notebook (can be saved Your source code, running results), a python web interface that integrates text (markdown), code, images, and formulas
3. Supports interactive data visualization and other graphical user interfaces
4. Support high-performance parallel computing
3. Running environment
There are many program libraries for data analysis and machine learning. These program libraries (such as : numpy, pandas, sckilearn, TensorFlow, etc.), it would be troublesome to configure and install it alone, and some packages (such as scipy) rely on many libraries; the official provides an integrated data analysis and machine learning development tool , that is, anaconda installation: download the latest version from the official website, just install it under windows
Open:
Method 1, use the command
Use the cmd command line or Linux terminal to embed the command: jupyter The notebook will run two programs: the IPython service program and the jupyter notebook web interface, and then the code can be written in the interface
Note] The IPython server is where the program runs, and jupyter notebook only provides An interactive interface, if you turn off the IPython service program (ctrl c in the terminal) jupyter notebook will be useless.
Several basic operations:
Double-click D: delete the current cell
Click M: Convert the current cell into a markdown document
Jupyter structure: It is composed of cells. The execution of each cell does not affect each other, but the data is shared
Method 2, open with anaconda interface
Method 3, open with pycharm
[Note] The compiler must select the python compiler in the anaconda directory, otherwise IPython cannot be opened Service Program

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),
