[已解决]求助正则表达式匹配规则

qianxin

用正则表达式匹配   “DK1-146”或者“T23-87”  这样的字符
匹配规则 r'（DK1|T\d｛1，2｝）-（\d｛1，3｝）这样子有问题吗？
我试了匹配“ehdjr52nhDK1-51676sjkw57h”和“sgshdjjT6-6djks826”

结果是“DK1”和“T6”
不知道是哪出问题了

>>> s = "ehdjr52nhDK1-51676sjkw57h sgshdjjT6-6djks826"
>>> s
'ehdjr52nhDK1-51676sjkw57h sgshdjjT6-6djks826'
>>> import re
>>> re.findall('.*?(DK1-\d+).*?', s)
['DK1-51676']
>>> re.findall('.*?(DK1-\d+|T\d{1,2}-\d+).*?', s)
['DK1-51676', 'T6-6']
>>> s = "DK1-56s5  djjT6-6826xxx"
