python 学习笔记——python globals()

# coding:utf-8
__author__ = 'taohao'
a = set()
class test1:

def __init__(self):
pass

def a1(self):
pass

def b1(self):
pass

class test2:

def __init__(self):
pass

@classmethod        # 注意这里需要用用装饰器装饰一下，不然在外面用globals访问时会报错
def a2(self):
print "test2-------a2"

def b2(self):
pass

g = globals()
print type(g['test2'])   #输出 <type 'classobj'>
g['test2'].a2()          # 如果a2()函数不用装饰器装饰则会报错：TypeError: unbound method a2() must be called with test2 instance as f# irst argument (got nothing instead)

print g
