The nonlocal keyword in Python allows nested functions to modify variables from an enclosing function's scope. This tutorial covers its usage, differences from global, and practical applications in managing enclosed scope variables. Unlike global, nonlocal targets variables in the nearest enclosing ...

关键字nonlocal用来在函数或者其他作用域中使用外层(非全局变量)。换句话说,nonlocal用来声明变量不处于当前的函数当中,需要解释器在包含这个函数的函数中寻找nonlocal声明的同名变量,找到后就可以使用这个对象对应的值在当前函数中进行操作。 它用来在部分情况下代替global关键字,防止滥用。 不使用nonlocal 代码语言:javas...
