爬虫出现TypeError: cannot use a string pattern on a bytes-like object报错

import urllib.request
import re
data = urllib.request.urlopen("https://edu.csdn.net/huiyiCourse/detail/253").read()
pat = "<p>(\d*?)</p>"
rst = re.compile(pat).findall(data)
print(rst)

爬虫出现报错：TypeError: cannot use a string pattern on a bytes-like object
原因：解码问题报错

解决方案：
需要在对应的数据中加上 .decode(“utf-8”)

data = urllib.request.urlopen("https://edu.csdn.net/huiyiCourse/detail/253").read().decode("utf-8")
