'''
创建一个类似于通讯录功能的类，要求如下
1.通讯录要有名字，如'xxx的通讯录'
2.类能实现一般的通讯功能，例如:
  联系方式录入，修改，删除，精确查找，匹配姓名，显示目前有多少联系人。（暂时假定一个人只有一个联系方式）
3.类有模拟拨号功能
4.类支持通讯录导出功能，能把当前的通信录导出到指定文件

# 设置通讯录名字

t1.showTname()
# 向通讯录添加记录
t1.load("张三",346542364)
t1.load('李四',464167649)
t1.load('王五',764846411)
t1.show_book()
# 修改记录 的key
t1.change_name("张三","张十三")
t1.show_book()
# 修改记录 的value
t1.change_number('张十三', 164458317)
t1.show_book()
# 按关键字查询
t1.match("张")
t1.match('赵')
# 查询总共有多少条记录
print(t1.show_member())
# 拨打电话
t1.calling(164458317)
# 导出通讯录到某个文件中
t1.write_out('./txl.txt')
