re正则表达式讲解—初步认识

# f = open(r"C:\Users\LENOVO\Desktop\模特.txt",‘r‘)

# 1.常规提取文档内容方法
# contacts = []
# for i in f:
#     name,local,height,weight,telephone = i.split()
#     if len(telephone) == 11 and telephone.isdigit():
#
#
#         contacts.append(telephone)
#
# print(contacts)

# 2.运用re模块快速提取文档内容

import re
f = open(r"C:\Users\LENOVO\Desktop\模特.txt",‘r‘)
date = f.read()

print(re.search("1[0-9]{10}",date))  #找到第一个
print(re.findall("1[0-9]{10}",date)) # 找到所有符合条件的
