回溯（最后一次调用）：文件“<stdin>”，第 1 行，在 <module>

Question

我只是输入了一些代码：

import urllib
response=urlib.urlopen(“www.baidu.com”)

比错误码：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib.py", line 87, in urlopen
    return opener.open(url)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib.py", line 213, in open
    return getattr(self, name)(url)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib.py", line 469, in open_file
    return self.open_local_file(url)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib.py", line 483, in open_local_file
    raise IOError(e.errno, e.strerror, e.filename)
IOError: [Errno 2] No such file or directory: ‘www.baidu.com’

Answer 1

URL前面需要有"http://"或"https://"，所以试试：

import urllib
response=urlib.urlopen('http://www.baidu.com')

或者：

import urllib
response=urlib.urlopen('https://www.baidu.com')

注意：使用' 或" 代替” 和“。
