*在外层作用域中,不能访问内层作用域中的数据* 在Python 中,模块(module),类(class)、函数(def、lambda)会产生新的作用域 条件判断(if……else)、循环语句(for x in data)、异常捕捉不会产生作用域 在分支,循环,异常处理中声明的变量,作为范围是属于当前作用域的 10.3 全局变量和局部变量 在函数中定义

python -m nuitka --module some_package --include-package=some_package Note The inclusion of the package contents needs to be provided manually, otherwise, the package is mostly empty. You can be more specific if you want, and only include part of it, or exclude part of it, e.g. with...
