对python读写文件去重、RE、set的使用详解

如下所示：#-*-coding:utf-8-*-fromdatetimeimportdatetimeimportredefMain():sourcr_dir='/data/u_lx_data/fudan/muying/m

如下所示：

# -*- coding:utf-8 -*-
 
from datetime import datetime
import re
 
 
def Main():
 sourcr_dir = '/data/u_lx_data/fudan/muying/muying_11yue_all.txt'
 target_dir = '/data/u_lx_data/fudan/muying/python/uid_regular_get.txt'
 
 uset = set() #去重
 
 print("开始。。。。。")
 print(datetime.now().strftime('%Y-%m-%d %H:%M:%S'))
 
 with open(target_dir, 'w+') as f_write:
 with open(sourcr_dir, 'r') as f_scorce:
 for line in f_scorce:
 line = line.strip().split("\t")
