Package Into

什么是 “Package Into”?

“Package Into” 是一个常用于软件开发和系统设计中的术语,意指将一组功能、数据或逻辑“打包”进一个模块、包、类或组件中。 这种做法有助于提高代码的可维护性、复用性和清晰度。

常见应用场景

为什么重要?

将功能“打包”不仅是一种组织代码的方式,更是面向对象和模块化设计思想的体现。 它帮助开发者:

示例代码

JavaScript (ES6 模块)

// mathUtils.js
export function add(a, b) {
  return a + b;
}

// main.js
import { add } from './mathUtils.js';
console.log(add(2, 3)); // 5

Python (包结构)

# mypackage/__init__.py
from .calculator import add

# mypackage/calculator.py
def add(a, b):
    return a + b

# main.py
from mypackage import add
print(add(2, 3))  # 5
