tuple元组输出

Question

#-*- coding:utf-8 -*-

data= ((u'13800138000',), (u'13800138111',), (u'13800138222',), (u'13800138333',))

for string in data:
    print str(string[0])
    payload = {'phone': str(string[0])}
    print payload

在payload中怎么才能正常输出
13800138000
13800138111
13800138333
而不是
'13800138000'
'13800138111'
'13800138333'
