Question

我正在使用BeautifulSoup4制作网页抓取工具并请求库。我在BeautifulSoup工作时遇到了一些麻烦，但得到了一些帮助，并且能够解决这个问题。现在我遇到了一个新问题，我不知道如何解决它。我正在使用请求2.2.1，我正在尝试在Python 3.1.2上运行该程序。当我这样做时，我得到一个追溯错误。

这是我的代码：

from bs4 import BeautifulSoup
import requests

url = input("Enter a URL (start with www): ")
link = "http://" + url
page = requests.get(link).content
soup = BeautifulSoup(page)

for url in soup.find_all('a'):
    print(url.get('href'))
    print()

和错误：

Enter a URL (start with www): www.google.com
Traceback (most recent call last):
  File "/Users/user/Desktop/project.py", line 8, in <module>
    page = requests.get(link).content

    return request('get', url, **kwargs)

    prep = self.prepare_request(req)
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/site-packages/requests-2.2.1-py3.1.egg/requests/sessions.py", line 287, in prepare_request
    hooks=merge_hooks(request.hooks, self.hooks),

    url = str(url)
TypeError: 'tuple' object is not callable

我已经做了一些寻找，当其他人得到这个错误时（主要是在django中）有一个逗号丢失，但我不确定在哪里放一个逗号？任何帮助将不胜感激。

请求：TypeError：'tuple'对象在python 3.1.2中不可调用
