Python_API_Built-in Functions_locals

API文档：

locals()

      Update and return a dictionary representing the current local symbol table. Free variables are returned by locals() when it is called in function blocks, but not in class blocks.

     Note

         The contents of this dictionary should not be modified; changes may not affect the values of local and free variables used by the interpreter.

       描述：

             这个方法返回一个字典。该字典中存储局部名字空间（当前函数或是类方法）的变量，包括函数的参数。

例子：

#! /usr/bin/env python
#coding=utf-8

aa='ccc'

class TestC:
    b = 'bb'
    
    def f(self,x):
        print locals()

def fun(param):
    x = 0
    print locals()
    
fun('cc')

t = TestC()
t.f('g')

输出：

{'x': 0, 'param': 'cc'}
{'x': 'g', 'self': <__main__.TestC instance at 0x01AC8AA8>}
