# 匹配由单个空格分隔的任意单词对,也就是姓和名

 import re

 patt = '[A-Za-z]+ [A-Za-z]+'  # 方法一 +加号操作符匹配它左边的正则表达式至少出现一次的情况
 # patt = '[A-Za-z]+[ A-Za-z]+'  # 方法二
 5 # patt = '[A-Za-z]+\s[A-Za-z]+' # 方法三   \s匹配空白 
 name1 = 'zhang san'
 name2 = 'li si'
 name3 = 'wang ermazi'

 m = re.match(patt, name1)
 m1 = re.match(patt, name2)
 m2 = re.match(patt, name3)
 if m is not None:
     print(m.group())
 if m is not None:
     print(m1.group())
 if m is not None:
     print(m2.group())
