Why do I get a recursion error with BeautifulSoup and IDLE? (1 个回答)

已关闭 8 年前。

我正在使用 Beautiful soup 从 Weather Underground 网站上抓取数据。我能够获得我想要的确切数据并将其分配给变量 dayTemp 。但是当我尝试使用 print dayTemp 打印它时。我收到以下错误:

 Traceback (most recent call last):
  File "<pyshell#47>", line 1, in <module>
    print dayTemp
  File "C:\Python27\lib\idlelib\rpc.py", line 595, in __call__
    value = self.sockio.remotecall(self.oid, self.name, args, kwargs)
  File "C:\Python27\lib\idlelib\rpc.py", line 210, in remotecall
    seq = self.asynccall(oid, methodname, args, kwargs)
  File "C:\Python27\lib\idlelib\rpc.py", line 225, in asynccall
    self.putmessage((seq, request))
  File "C:\Python27\lib\idlelib\rpc.py", line 324, in putmessage
    s = pickle.dumps(message)
  File "C:\Python27\lib\copy_reg.py", line 74, in _reduce_ex
    getstate = self.__getstate__
RuntimeError: maximum recursion depth exceeded  

我正在使用span.string从整个元素中获取整数值。变量的类型dayTemp是 <class 'bs4.element.NavigableString'>

空闲似乎无法腌制dayTemp。您可以尝试将其显式转换为 Unicode 字符串:

print unicode(dayTemp)
