想要获取invite_uuid=之后的那一串字符：

url = "http://www.baidu.com/public_share?rule_type=member&invite_uuid=72665347-35b1-4326-b37d-078d4f8f3f73&" print (url.index("&")) r1 =url[url.index("&")+1:-1] print(r1) r1.index('=') print(r1[r1.index('=')+1:-1]) 返回：72665347-35b1-4326-b37d-078d4f8f3f7 方法二：正则表达式：很好用

string = "xxxxxxxxxxxxxxxxxxxxxxxx entry '某某内容' for aaaaaaaaaaaaaaaaaa" result = re.findall(".*entry(.*)for.*", string) for x in result:     print(x) 》》》'某某内容' 但是此方法如果在string字符串中有多个，就只会取最后一个的
