from urllib import request
import urllib
#對中文解碼成URL的形式
wed = {"wd":"北京"}
url = "https://www.baidu.com/s?"
urll="&tn=78040160_5_pg&ch=8"
wdd = urllib.parse.urlencode(wed)
url = url+wdd+urll
#構造處理器對象
req = request.Request(url)
#發送請求，並讀取內容
response = request.urlopen(req).read().decode()
print(wdd)
print(response)結果：
