**extra表示把extra这个dict的所有key-value用关键字参数传入到函数的**kw参数,kw将获得一个dict。 5.命名关键字参数 对于关键字参数,函数的调用者可以传入任意不受限制的关键字参数。至于到底传入了哪些,就需要在函数内部通过kw检查。 仍以person()函数为例,我们希望检查是否有city和job参数: 1defperson(name, a...
L ( Local):函数内的区域,包括局部变量和形参。 E(Enclosing):外面嵌套函数区域,常见的是闭包函数外的函数。 G( Global):全局作用域。 B( Built-in): 内建作用域。 Python中变量是采用L -> E->G一>B的规则查找 当Python检索变量的时候,先是在局部中查找,如果找不到,便会去局部外的局部找(例如闭包),...
