re.findall()从html去除带有\n数据不换行

本文主要是介绍re.findall()从html去除带有\n数据不换行，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

原始数据：

{"errno":0,"data":{"...,"key":"-----BEGIN PUBLIC KEY-----\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDvEpk7iB6BF8ZLXG0vSMr7Qedl\nB9Q4c9qrqiNziUt3RokRkr7pHxWlelQPC3JIMs+UvMkabTkDNE4pvx\/DkFWEMzzu\nHuDeenKNo1Ywymf8A6EtQIEL7MQpUaszPx6\/u5YqLVvjN7fyvF5LSVgtzjYhTTHK\nhTJF2R5dTkO3VswLVwIDAQAB\n-----END PUBLIC KEY-----\n"},"errmsg":""}

re.findall('"key":"(.*?)"', html)

print(re.findall('"key":"(.*?)"', html))re.findall给数据改成了\\n
['-----BEGIN PUBLIC KEY-----\\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDvEpk7iB6BF8ZLXG0vSMr7Qedl\\nB9Q4c9qrqiNziUt3RokRkr7pHxWlelQPC3JIMs+UvMkabTkDNE4pvx\\/DkFWEMzzu\\nHuDeenKNo1Ywymf8A6EtQIEL7MQpUaszPx6\\/u5YqLVvjN7fyvF5LSVgtzjYhTTHK\\nhTJF2R5dTkO3VswLVwIDAQAB\\n-----END PUBLIC KEY-----\\n']

re.findall('"key":"(.*?)"', html)[0] 

print(re.findall('"key":"(.*?)"', html)[0])看似好像改回来了，实际好像并没有改回来
-----BEGIN PUBLIC KEY-----\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDvEpk7iB6BF8ZLXG0vSMr7Qedl\nB9Q4c9qrqiNziUt3RokRkr7pHxWlelQPC3JIMs+UvMkabTkDNE4pvx\/DkFWEMzzu\nHuDeenKNo1Ywymf8A6EtQIEL7MQpUaszPx6\/u5YqLVvjN7fyvF5LSVgtzjYhTTHK\nhTJF2R5dTkO3VswLVwIDAQAB\n-----END PUBLIC KEY-----\n

还是有必要替换一下，

re.findall('"key":"(.*?)"', html)[0].replace('\\n', '\n')

-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDvEpk7iB6BF8ZLXG0vSMr7Qedl
B9Q4c9qrqiNziUt3RokRkr7pHxWlelQPC3JIMs+UvMkabTkDNE4pvx\/DkFWEMzzu

-----END PUBLIC KEY-----
