Python 3 代码 正常执行，希望采纳

# coding:utf8

from urllib import request

from http import cookiejar

url = "http://www.baidu.com"

print("第一种方法")

response1 = request.urlopen(url)

print(response1.getcode())

print(len(response1.read()))

print("第二种方法")

request2 = request.Request(url)

request2.add_header('user-agent', 'Mozilla/5.0')

response2 = request.urlopen(request2)

print(response2.getcode())

print(len(response2.read()))

print("第三种方法")

cj = cookiejar.CookieJar()

opener = request.build_opener(request.HTTPCookieProcessor(cj))

request.install_opener(opener)

response3 = request.urlopen(url)

print(response3.getcode())

print(response3.read())

print(cj)

不知道对不对，反正运行出来是这样 第一种方法  200   8405 第二种方法 200 8405 第三种方法200 <CookieJar[]>    8405
# coding:utf8
import urllib
import urllib.request
import http.cookiejar
url="http://www.baidu.com"
print ('第一种方法')
response1= urllib.request.urlopen(url)
print (response1.getcode())
print (len(response1.read()))
 
print ('第二种方法')
request=urllib.request.Request(url)
request.add_header("user-agent","Mozilla/5.0")
response2=urllib.request.urlopen(request)
print (response2.getcode())
print (len(response2.read()))
 
print ('第三种方法')
cj=http.cookiejar.CookieJar()
opener=urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
urllib.request.install_opener(opener)
response3=urllib.request.urlopen(url)
print (response3.getcode())
print (cj)
print (len(response3.read()))

我也是遇到这个问题，请问你的解决没有？

python3.x版本print是函数调用需要print()
