function/method help

[myv5285]

I am new to python, trying to work on requests module

Need to use get and post method. But not sure what arguments are needed to be passed - Can you help me to find out.

python 3.5

import requests, inspect 
inspect.getfullargspec(requests.get) 
FullArgSpec(args=['url', 'params'], varargs=None, varkw='kwargs', defaults=(None,), kwonlyargs=[], kwonlydefaults=None, annotations={})

===But am looking for what params are allowed for each method
This url helps
https://www.w3schools.com/python/ref_requests_get.asp

The above URL shows me what am interested but trying to see a way to get those.

tried help/dir but no luck

Please help experts.

you can use help, but it will depend on the doc-string provided. Of course you can consult also the docs/tutorials provided by package author.
Inspecting just the signature will not always be helpful, because function may take arbitrary arguments, like in this case - *kwargs

so, back to help
help(requests.get)

Output:
Help on function get in module requests.api:

get(url, params=None, **kwargs)
    Sends a GET request.
    
    :param url: URL for the new :class:`Request` object.
    :param params: (optional) Dictionary, list of tuples or bytes to send
        in the body of the :class:`Request`.
    :param \*\*kwargs: Optional arguments that ``request`` takes.
    :return: :class:`Response <Response>` object
    :rtype: requests.Response

so, param *kwargs will hold the optional rguments that requets takes.
look at help(requests.request)

help(requests.request)

Output:
Help on function request in module requests.api:

request(method, url, **kwargs)
    Constructs and sends a :class:`Request <Request>`.
    
    :param method: method for the new :class:`Request` object.
    :param url: URL for the new :class:`Request` object.
    :param params: (optional) Dictionary, list of tuples or bytes to send
        in the body of the :class:`Request`.
    :param data: (optional) Dictionary, list of tuples, bytes, or file-like
        object to send in the body of the :class:`Request`.
    :param json: (optional) A JSON serializable Python object to send in the body of the :class:`Request`.
    :param headers: (optional) Dictionary of HTTP Headers to send with the :class:`Request`.
    :param cookies: (optional) Dict or CookieJar object to send with the :class:`Request`.
    :param files: (optional) Dictionary of ``'name': file-like-objects`` (or ``{'name': file-tuple}``) for multipart encoding upload.
        ``file-tuple`` can be a 2-tuple ``('filename', fileobj)``, 3-tuple ``('filename', fileobj, 'content_type')``
        or a 4-tuple ``('filename', fileobj, 'content_type', custom_headers)``, where ``'content-type'`` is a string
        defining the content type of the given file and ``custom_headers`` a dict-like object containing additional headers
        to add for the file.
    :param auth: (optional) Auth tuple to enable Basic/Digest/Custom HTTP Auth.
    :param timeout: (optional) How many seconds to wait for the server to send data
        before giving up, as a float, or a :ref:`(connect timeout, read
        timeout) <timeouts>` tuple.
    :type timeout: float or tuple
    :param allow_redirects: (optional) Boolean. Enable/disable GET/OPTIONS/POST/PUT/PATCH/DELETE/HEAD redirection. Defaults to ``True``.
    :type allow_redirects: bool
    :param proxies: (optional) Dictionary mapping protocol to the URL of the proxy.
    :param verify: (optional) Either a boolean, in which case it controls whether we verify
            the server's TLS certificate, or a string, in which case it must be a path
            to a CA bundle to use. Defaults to ``True``.
    :param stream: (optional) if ``False``, the response content will be immediately downloaded.
    :param cert: (optional) if String, path to ssl client cert file (.pem). If Tuple, ('cert', 'key') pair.
    :return: :class:`Response <Response>` object
    :rtype: requests.Response
    
    Usage::
    
      >>> import requests
      >>> req = requests.request('GET', 'https://httpbin.org/get')
      <Response [200]>

Further you can inspect the source code and also the docs

Thanks for the reply

But I am interested in finding what are the args/kwargs GET method can take

But you said help(request.request)

How do I know it should be requests.requests

Assuming if I look for other module , will that be help(module.module) ??

But you said help(request.request)

How do I know it should be requests.requests

Because it's in the docstring for requests.get:

:param \*\*kwargs: Optional arguments that request takes.

Then, I looked at the source code, to confirm my understanding.


As I said - it's not always as simple as just using help() - it may be that function/method takes arbitarry arguments - e.g. *args, **kwargs, the docstring may be poorly written, etc. You may need to look at the source code or other resources like documentation (assuming it's not genereated from doc-strings), tutorials, etc.
