蠢新刚刚学习500 lines or less，就被一个非常简单的问题难住了

def fetch(url):
    sock = socket.socket()
    sock.connect(('xkcd.com', 80))
    request = 'GET {} HTTP/1.0\r\nHost: xkcd.com\r\n\r\n'.format(url)
    sock.send(request.encode('ascii'))
    response = b''
chunk = sock.recv(4096)
    while chunk:
        response += chunk
        chunk = sock.recv(4096)

    # Page is now downloaded.
links = parse_links(response)
    q.add(links)使用pycharm想要运行时，socket下一直提示unresolved reference,该怎么解决啊

居然是因为没有import,
