pythonscripting language

The naming of python originates from a script screenplay, which causes the dialog box to be repeated verbatim every time it is run. Written by the famous "Turtle Uncle" Guido van Rossum during the Christmas period of 1989.

Python provides us with a very complete basic code library, covering a large number of contents such as networks, files, GUIs, databases, texts, etc. It is vividly called a "built-in battery".
In addition to the built-in libraries, Python also has a large number of third-party libraries, that is, Dingxi developed by others for your use. Of course, if the code you develop is well encapsulated, it can also be used as a third-party library for others to use.

Why python is a scripting language

Python is an interpreted language. When the code is executed, it will be translated line by line into machine code that the CPU can understand.
Advantages: Elegant, clear, efficient, simple
Disadvantages: slow running speed , code cannot be encrypted

Python is cross-platform, that is, interoperability.
It can run on Windows, Mac and various Linux/Unix systems. For example: if you write a Python program on Windows, it can also run on Linux.

Python is an object-oriented language, and everything in Python is an object.

Scripting Language
Definition: In order to shorten the traditional processes.

Script language, also known as extended language, or dynamic language, is a programming language used to control software applications. Usually saved as text and only interpreted or compiled when called.

Features: The syntax is simple, generally saved in text form, and does not need to be compiled into a target program, and is directly interpreted when calling.

Common scripting languages include: cmd command, JavaScript, VBScript, perl, PHP, Pyhton, Ruby

Extension
The heart of the computer, the CPU only recognizes machine commands
So, although different programming languages are very different, they all have to be "translated" into machine commands that the CPU can execute.
Different programming languages, for the same event, the amount of code is also very different. For example:

To complete the same task, C language requires 1,000 lines of code, JAVA may only need 100 lines, and Python only needs 20 lines .
However, the price of less code is slow running speed. C language takes 1 second, JAVA may take 2 seconds, and Python may take 10 seconds.

Python vs. C : Learning Curves and Ease of UseApr 19, 2025 am 12:20 AM

Python 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 AM

Python 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 AM

Python'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 AM

Whether 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 AM

Python 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 AM

Is 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 AM

Key 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 AM

Python 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.
