The things that python needs to install are: 1. Python development environment "sde"; 2. Python integrated development environment "IDE"; 3. Python compiler.
#What do I need to install to learn python? For friends who have relatively little contact with programming, there are several terms that must be understood, such as development environment, IDE, code editor, compiler, debugger, etc. I will first list the explanations of several important words.
1. Glossary
Development environment:
Software Development Environment (SDE) It refers to a set of software used to support the engineering development and maintenance of system software and application software based on basic hardware and digital software, referred to as SDE. It consists of software tools and environment integration mechanisms. The former is used to support the related processes, activities and tasks of software development, and the latter provides unified support for tool integration and software development, maintenance and management.
IDE:
Integrated Development Environment (IDE, Integrated Development Environment) is an application used to provide a program development environment, generally including a code editor, compiler, Tools such as debuggers and graphical user interfaces. It is an integrated development software service suite that integrates code writing functions, analysis functions, compilation functions, debugging functions, etc. All software or software packages (groups) with this feature can be called integrated development environments.
Compiler:
Simply put, a compiler translates "one language (usually a high-level language)" into "another language (usually a low-level language) language)" program. The main workflow of a modern compiler: source code → preprocessor → compiler → object code → linker → executables. High-level computer languages ??are easy for people to write, read, communicate, and maintain. Machine language is something that computers can directly interpret and run. The compiler takes an assembly or high-level computer language source program (Source program) as input and translates it into an equivalent program in the target language (Target language) machine code. The source code is generally a high-level language (High-level language), such as Pascal, C, C, Java, Chinese programming, etc. or assembly language, while the target is the object code (Object code) of machine language, sometimes also called machine code ( Machine code). For high-level languages ??such as C# and VB, the function completed by the compiler at this time is to compile the source code (SourceCode) into the bytecode (ByteCode) of the universal intermediate language (MSIL/CIL). During the final run, through the conversion of a common language runtime library, the programming is finally machine code (NativeCode) that can be directly calculated by the CPU.
To put it simply, taking our common JAVA language as an example, if you want to write a program, if JDK is already installed on your computer, then you don’t actually need any other software. Implement some functions. Some people may ask, I think everyone uses eclipse to write JAVA. Yes, most people use eclipse to write JAVA. But you must know that that software is called an IDE, or it is an editor. A simple version of eclipse is JDK will not be provided. JDK needs to be installed separately. This JDK is the development environment. If you want to compile and run the code you have written, it needs the support of the JDK development environment, and eclipse provides it for you to edit. , debugging, and using JDK to compile programs, that is to say, which editor you use does not affect the writing of your program, and these editors allow you to improve efficiency and facilitate debugging. These are optional, and A development environment is required.
2. Python development environment
Python is actually a little different from other programming languages. It is a scripting language. We can also call it interpretation. Type language. Therefore, the running process of python is different from our traditional languages, such as compiled languages ??such as C and C. The running of python is actually an interpretation process, so it requires an interpreter . If you want to run a Python program, then the Python development environment is essential. The Python development environment download address:

Once you have a development environment, you need software such as an editor. In fact, when you install the Python development environment, it already comes with an editor called IDLE, but to be honest, this editor is really not very comfortable to use, especially when editing relatively large projects. Moreover, the all-purpose Notepad can also edit Python, but we definitely can’t do that, right? Then I will recommend several editors that can edit python. Eclipse: Eclipse is an open source, Java-based extensible development platform. By itself, it is just a framework and a set of services for building development environments through plug-in components. Fortunately, Eclipse comes with a standard set of plug-ins, including the Java Development Kit (JDK). Eclipse is not limited to writing JAVA, it can also write C, python and other programs, and Eclipse is very comfortable in writing Python and is worth recommending.PyCharm:
PyCharm is a Python IDE with a set of tools that can help users improve their efficiency when developing in the Python language, such as debugging, syntax highlighting, Project management, code jumping, Intelligent prompts, auto-completion, unit testing, and version control. In addition, the IDE provides some advanced features to support professional web development under the Django framework. PyCharm is a strong player in writing and debugging Python. The software is simple to use and powerful, and it is worth recommending.
VS Code:
Visual Studio Code (VS Code / VSC for short) is a free and open source modern lightweight code editor that supports syntax highlighting for almost all mainstream development languages. , intelligent code completion, custom hotkeys, bracket matching, code snippets, code comparison Diff, GIT and other features, supports plug-in extensions, and is optimized for web development and cloud application development. The software supports Win, Mac and Linux across platforms. This software is so beautiful that I couldn’t resist posting a picture.

PHP calls AI intelligent voice assistant PHP voice interaction system construction
Jul 25, 2025 pm 08:45 PM
User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.
How to use PHP combined with AI to achieve text error correction PHP syntax detection and optimization
Jul 25, 2025 pm 08:57 PM
To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X

String lists can be merged with join() method, such as ''.join(words) to get "HelloworldfromPython"; 2. Number lists must be converted to strings with map(str, numbers) or [str(x)forxinnumbers] before joining; 3. Any type list can be directly converted to strings with brackets and quotes, suitable for debugging; 4. Custom formats can be implemented by generator expressions combined with join(), such as '|'.join(f"[{item}]"foriteminitems) output"[a]|[
Essential HTML Tags for Beginners
Jul 27, 2025 am 03:45 AM
To get started with HTML quickly, you only need to master a few basic tags to build a web skeleton. 1. The page structure is essential, and, which is the root element, contains meta information, and is the content display area. 2. Use the title. The higher the level, the smaller the number. Use tags to segment the text to avoid skipping the level. 3. The link uses tags and matches the href attributes, and the image uses tags and contains src and alt attributes. 4. The list is divided into unordered lists and ordered lists. Each entry is represented and must be nested in the list. 5. Beginners don’t have to force memorize all tags. It is more efficient to write and check them while you are writing. Master the structure, text, links, pictures and lists to create basic web pages.
