python处理大数据文件，set、enumerate使用，python传参，获取文件路径_python set可以enumerate

###   enumerate(ad_set,start=1)

###   start=1：指定索引起始值

#-*- coding:utf-8 -*-
#唯一号码转家庭、非家庭
#编写者：zqm
#日期：20170810
#功能：分别找出家庭，非家庭用户，家庭的编号转jz编号，非家庭重新编号且相同编号相同
######################################################################
# 备注：
#       File_target_zhengq_temp(临时文件)是处理的文件中的政企数据
#
# 调用方式：python Jzad_jiat_zhengq.py /zqm/处理的文件.txt
#
# 注意：
#      此程序只适用于ad在File_deal文件的第一列，如果不在第一列，请酌情修改程序
