Question

Python 正则表达式匹配两个字符之间的字符

Answer 1

1.首先p.search(s)只会找第一个匹配的字符串2.其次p.findall(s)会记录匹配的组，而(19|20)代表一个组，应该改成(?:19|20)以下代码可以满足你的要求：#-*-coding:utf-8-*-from__future__importprint_function,divisionimportres='ID:042SEX:MDOB:1967-08-17Status:Active1968'p=re.compile(r'(?:19|20)\d{2}')#s='ID:042SEX:MDOB:1967-08-17Status:Active1968'all_items=re.findall(p,s)map(print,all_items)print(all_items)
