...如果想在另一个函数中更改global line,update_variables()应该在分配变量之前使用global。...function update_variables() print(global_variable_1) # prints 11 print(global_variable_2) # prints 2 以上就是python...变量声明为全局变量的两种方法,希望对大家有所帮助。
闭包的本质是一个函数,包含两个部分:内部函数体本身以及对外部函数变量的引用,这个变量(自由变量: free variables)的引用不会因为外部函数执行完毕而消失。 构成闭包的三个条件: 1、函数内嵌函数; 2、内函数引用外函数定义的变量 3、外函数返回内函数的引用。 变量作用域 赋值在前,引用在后 # ---同作用域内-...
