Python 搜索(search)

import re

print(re.match("abc","abc xyz"))
print(re.match("xyz","abc xyz"))  #匹配必须从第一个开始，

print(re.search("abc","abc xyz")) #包含就可以
print(re.search("xyz","abc xyz"))

import re

searchobj=re.search(r"(.*)-is-(.*)","abc xyz-is-go")  #在这里，search和match无区别
print(searchobj)
print(searchobj.group())
print(searchobj.group(0))  #abc xyz-is-go
print(searchobj.group(1))  #abc xyz
print(searchobj.group(2))  #go
