API description

query(query_string, secure=False, container=u'namedtuple', verbose=False,
      user_agent=u'duckduckpy 0.2', no_redirect=False, no_html=False,
      skip_disambig=False)

Generates and sends a query to DuckDuckGo API.

Arguments:

query_string	Query to be passed to DuckDuckGo API.
secure	Use secure SSL/TLS connection. Default - False. Syntactic sugar is secure_query function which is passed the same parameters.
container	Indicates how dict-like objects are serialized. There are two possible options: namedtuple and dict. If ‘namedtuple’ is passed the objects will be serialized to namedtuple instance of certain class. If ‘dict’ is passed the objects won’t be deserialized. Default value: ‘namedtuple’.
verbose	Don’t raise any exception if error occurs. Default value: False.
user_agent	User-Agent header of HTTP requests to DuckDuckGo API. Default value: ‘duckduckpy 0.2’
no_redirect	Skip HTTP redirects (for !bang commands). Default value: False.
no_html	Remove HTML from text, e.g. bold and italics. Default value: False.
skip_disambig	Skip disambiguation (D) Type. Default value: False.

Raises:

DuckDuckDeserializeError	JSON serialization failed.
DuckDuckConnectionError	Something went wrong with httplib operation.
DuckDuckArgumentError	Passed argument is wrong.

Returns:

Container depends on container parameter. Each field in the response is converted to the so-called snake case.

Usage

>>> from duckduckpy import query
>>> response = query('Python') # namedtuple is used as a container
>>> response
Response(redirect=u'', definition=u'', image_width=0, ...}
>>> type(response)
<class 'duckduckpy.api.Response'>
>>> response.related_topics[0]
Result(first_url=u'https://duckduckgo.com/Python', text=...)
>>> type(response.related_topics[0])
<class 'duckduckpy.api.Result'>

>>> response = query('Python', container='dict') # dict as the container
>>> type(response)
<type 'dict'>
>>> response
{u'abstract': u'', u'results': [], u'image_is_logo': 0, ...}
>>> type(response['related_topics'][0])
<type 'dict'>
>>> response['related_topics'][0]
{u'first_url': u'https://duckduckgo.com/Python', u'text': ...}
