And*_*pez 2 python regex numbers brackets between
当我的值在单词“PIC”和“.”之间时,我需要帮助创建一个正则表达式来获取括号之间的数字。
我得到了这个记录,需要能够在 () 之间提取值
PIC S9(02)V9(05). I need this result "02 05"
PIC S9(04). I need this result "04"
PIC S9(03). I need this result "03"
PIC S9(03)V9(03). I need this result "03 03"
PIC S9(02)V9(03). I need this result "02 03"
PIC S9(04). I need this result "04"
PIC S9(13)V9(03). I need this result "13 03"

我尝试了以下但它不起作用。
s = "PIC S9(02)V9(05)."
m = re.search(r"\([0-9]+([0-9]))\", s)
print m.group(1)

您可以使用re.findall()来查找括号内的所有数字:
>>> import re
>>> l = [
... "PIC S9(02)V9(05).",
... "PIC S9(04).",
... "PIC S9(03).",
... "PIC S9(03)V9(03).",
... "PIC S9(02)V9(03).",
... "PIC S9(04).",
... "PIC S9(13)V9(03)."
... ]
>>> pattern = re.compile(r"\((\d+)\)")
>>> for item in l:
... print(pattern.findall(item))
...
['02', '05']
['04']
['03']
['03', '03']
['02', '03']
['04']
['13', '03']

where \(and\)将匹配文字括号(需要用反斜杠转义,因为它们具有特殊含义)。(\d+)是匹配一个或多个数字的捕获组。
