import re
match = re.search(r'\d+','132gs')
if match:
  print match.group(0)
else:
  print "no match"
输出“123”
--------------------------------------------------------
 有这样的设计总有他的意图。
不过，发现Python的文档不大好。我现在也在学用正则表达式，我search的结果却不知
道怎么查出来。就只能
if (re.search(r'\d+','132gs')==None):
     pass
else:
    pass
这样处理吗？可不可以直接就得到132呢？
