Process finished with exit code 

添加如下代码：

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

# -*-coding:utf-8-*-


from urllib import request
import ssl

ssl._create_default_https_context = ssl._create_unverified_context

req = request.Request("https://www.baidu.com")

req.add_header('User-Agent',
               'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.62 Safari/537.36')

resp = request.urlopen(req)
resp = request.urlopen(req)

print(resp.read().decode('utf-8'))
