我有一个文件，其内容为：

01009700  Samsung  Samsung SGH-N625  GSM 1900,GSM 900  
01009800  Motorola  Motorola T194 EOTD  GSM 1900  

01009900  Option International

01010100  Sierra Wireless Sierra Wireless Aircard 750  GSM 1800,GSM 190  
0,GSM 900

我使用正则表达式，尝试从8位数字中提取任何内容，并在第一次出现GSM之前提取任何内容，例如：

01009700  Samsung  Samsung SGH-N625
01009800  Motorola  Motorola T194 EOTD
01009900  Option International
01009902  Option International
01009919  Option International
01010000  Sierra Wireless Sierra Wireless Aircard
01010100  Sierra Wireless Sierra Wireless Aircard

我尝试了\d{8}.+(GSM)?，但似乎不起作用。

什么是正确的正则表达式？

1 个答案:

答案 0 :(得分：4)

您可以使用

re.findall(r'\b(\d{8}.*?)\W*GSM', s)

请参见regex demo

详细信息

  • \b-单词边界（
  • (\d{8}.*?)-组1：八位数字，然后除换行符外的任何0+字符应尽可能少
  • \W*-任意0+个非单词字符
  • GSM-一个GSM子字符串。

Python demo：

import re
s="""01009700  Samsung  Samsung SGH-N625  GSM 1900,GSM 900
