从另一个模块访问全局变量

# module1.py
global_variable = "Hello, world!"

# module2.py
import module1

print(module1.global_variable)  # 输出：Hello, world!

// Module1.java
public class Module1 {
    public static String globalVariable = "Hello, world!";
}

// Module2.java
import Module1;

public class Module2 {
    public static void main(String[] args) {
        System.out.println(Module1.globalVariable);  // 输出：Hello, world!
    }
}

// module1.js
export const globalVariable = "Hello, world!";

// module2.js
import { globalVariable } from './module1.js';

console.log(globalVariable);  // 输出：Hello, world!
