python-re使用举例

 

 

代码：

import re

text = "JGood is a handsome boy, he is cool, clever, and so on..."
print(text)
m = re.match(r"(\w+)\s", text)
n = re.search(r"\shan(ds)ome\s", text)
if m:
    print("match: \"(\w+)\s\" ")
    print(m.group(0))
else:
    print 'not match'  

if n:
    print("search: \"\shan(ds)ome\s\"")
    print(n.group(0))
else:
    print 'not match'  

执行结果：

JGood is a handsome boy, he is cool, clever, and so on...
match: "(\w+)\s"
JGood
search: "\shan(ds)ome\s"
 handsome
