Python 跨文件跨进程使用全局变量

globalvar.py

abc = None
cba = None


def set_abc(value):
    global abc
    abc = value


def get_abc():
    global abc
    return abc

main.py

import globalvar 
import threading
import time
import t

globalvar.set_abc('123')
globalvar.cba = '321'

t1 = threading.Thread(target=t.show_data)
t1.setDaemon(True)
t1.start()

time.sleep(1)

print 'finish!'

t.py

import globalvar 

def get_data():
    print globalvar.get_abc()
    print globalvar.cba
