闭包函数

#作用域关系在函数定义阶段时就已经固定死了，与调用位置无关
# 即：在任意位置调用函数都需要跑到定义函数时寻找作用域关系

# def f1():
#     x=1
#     def inner():
#         print(x)
#
#     return inner
#
# func=f1()
#
# def f2():
#     x=111111
#     func()
#
# f2()

# 闭包函数：
# 闭指的是：该函数是一个内部函数
# 包指的是：指的是该函数包含对外部作用域（非全局作用域）名字的引用
# def outter():
#     x = 1
#     def inner():
#         print(x)
#
#     return inner
#
# f=outter()
#
# def f2():
#     x=1111111
#     f()
#
# f2()
#
#
# def f3():
#     x=4444444444444
#     f()
#
# f3()



# 为函数体传值的方式一：使用参数的形式
# def inner(x):

# inner(1)
# inner(1)
# inner(1)
# 为函数体传值的方式二：包给函数
