Python通过global实现多文件共享全局参数，方法

x = 6
def func():
    global x #定义外部的x
    x = 10
func()
print (x)
#输出10

def _init(): #初始化
    global  _global_dict
    _global_dict={}
def set_value(key,value):
    #定义一个全局变量
    _global_dict[key]=value
def get_value(key, defValue=None):
    #获得全局变量，不存在则返回默认值
    try:
        return _global_dict[key]
    except KeyError:
        return defValue

import glo
import glo2
glo._init()
glo.set_value('cho','game')
glo2.test() # 输出game 

import glo
def test():
	print(glo.get_value('cho')) 

import glo
import glo2
glo._init()

test = glo2.Test(1)
print('isLosgin：',glo.get_value('isLosgin'))
print(glo.get_value('isLosgin')())

import glo
class Test:
	id = 0
	def __init__(self,id):
		self.id = id
		glo.set_value('isLosgin',self.isLosgin)
	def isLosgin(self):
		print('id',self.id)
		return self.id == 1

isLosgin： <bound method Test.isLosgin of <glo2.Test object at 0x01C551D8>>
id 1
True
