Global variable after increment: 1 Global variable in file2: 1 1. 2. 可以看到,现在shared_var在两个文件中的值是连贯的。 小结 在多文件 Python 项目中,管理全局变量是一项重要技能。使用模块将全局变量集中管理是一种优秀的编程实践,不仅可以提升代码的可读性,还可以帮助减少潜在的错误和复杂性。 接下来,...
在上述示例中,modifyGlobalVariable函数内部定义了一个与全局变量globalVariable同名的局部变量,当在函数内部使用该变量时,实际上使用的是局部变量而不是全局变量。在函数外部,全局变量的值保持不变。 需要注意的是,局部变量的作用域仅限于定义它的函数内部,其他函数无法直接访问该局部变量。如果需要在多个函数之间共享...

In MAXScript, there are two classes of variables that you can create: "local" and "global" variables. When a variable is global, it means that the variable can be used anywhere in the program. The only place you cannot use a global variable is before you have defined it.For...
