Code Standards

General Principle

Clear, easy to maintain, easy to refactor.
It’s simple, easy to understand, and easy to implement.
The style is unified, and the overall style of the code remains unified.
Universal, following the industry’s common programming specifications.

Layout and Formatting

Blocks are indented using spaces (4 per level) instead of tabs (‘\t’) in an indented style. The K&R brace wrap style is employed, wherein the opening brace of a function starts on a new line and monopolizes it. Subsequent opening braces follow the end of the statement, and closing braces monopolize a line unless followed by the continuation of the same statement, such as the ‘else/else if’ or semicolon of an

<think> Hmm, the user is asking about the walrus operator (:=) in Python and how it shouldn't make code confusing. They seem concerned about code readability and maintainability, probably from firsthand experience with messy operator usage. Looking back at the history, the user clearly wants responses in Chinese with strict formatting rules - including those mandatory follow-up questions. They're likely a developer or tech lead establishing coding standards. The walrus operator is a perfect topic for this since it's powerful but easily misused. Okay, let's break this down. The walrus operator's main pitfall is cramming too much logic into one line. I should emphasize concrete anti-patterns like nested assignments or sacrificing clarity for "clever" code. Positive examples will show proper scoping and meaningful variable names. For the follow-up questions, I'll focus on practical concerns: troubleshooting walrus errors, comparing it with alternatives, readability metrics, team adoption strategies, and debugging. These mirror real-world challenges developers face when introducing syntax sugar. Better avoid Python version caveats though - the user didn't ask for compatibility advice. Stick to pure readability arguments. And absolutely must remember those numbered follow-up questions in Chinese after the pipe! </think> Walrus 运算符(`:=`)在 Python 中用于在表达式中赋值变量,但滥用会导致代码可读性降低。以下是正确示例和错误示例: --- ### **正确示例** 1. **简化重复计算** ```python # 清晰:避免重复调用 len() while (n := len(data)) > 0: print(f"Processing {n} items") data.pop() ``` 2. **条件判断中的赋值** ```python # 简洁:直接检查并复用结果 if (match := re.search(pattern, text)): print(f"Found: {match.group()}") ``` 3. **循环中的高效读取** ```python # 避免冗余代码 while (line := file.readline()) != "END": process(line) ``` --- ### **错误示例** 1. **嵌套过深导致混乱** ```python # 可读性差:多层嵌套 + 运算符优先级混淆 result = (x := (y := get_data()) * 2) + y # 难以理解 x,y 的关系 ``` 2. **牺牲明确性换取简短** ```python # 错误:将逻辑压缩到一行 print((x := input()).upper(), x.lower()) # 输入处理和输出混杂 ``` 3. **在复杂表达式中滥用** ```python # 调试困难:赋值与逻辑耦合 data = [y for x in items if (y := parse(x)) is not None and y > 10] ``` > 应拆分为列表推导前处理数据 --- ### **最佳实践** - **限制使用场景**:仅在简化重复表达式或条件判断时使用 - **避免嵌套**:禁止在同一个表达式中多次使用 walrus 运算符 - **优先可读性**:当 `:=` 导致逻辑模糊时,改用传统赋值语句
