'模块'对象没有属性'获取'？

from urllib import request
from bs4 import BeautifulSoup
def trade_spider(max_pages):
page = 1
while page <= max_pages:
    x = 16958 + int(page)
    url = 'http://mery.jp/' + str(x)
    source_code = request.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text)
    print(soup)
    break

trade_spider(2)

当我尝试在Python3.4中运行上面的代码时，收到一条错误消息，内容如下：

File "web_crawler.py", line 15, in <module>
trade_spider(2)
File "web_crawler.py", line 9, in trade_spider
source_code = request.get(url)
AttributeError: 'module' object has no attribute 'get'

有想法该怎么解决这个吗？先感谢您。
