For python, what does it mean for

Question

I tries to use Requests library in python for crawling, I first imported the requests module,and then I use get function to call the website for getting a response named r, but I can not understand why the type of r is class,could you please tell me why ,thank you very much.

I also want to check the request header, I checked some documents, it says that I can use r.request.headers, what does the request here mean, is it a method?

>>> import requests
>>> r=requests.get("http://www.baidu.com")
>>> type(r)
<class 'requests.models.Response'>

this is simply a class....follow this link to het idea about how to use get...https://stackoverflow.com/questions/27803503/get-html-using-python-requests — Amrit, Nov 09 '17 at 04:10
check the output of `help(r)` . You'll get a clear picture of what is the base class, from where it is inherited from and few definitions! — Keerthana Prabhakaran, Nov 09 '17 at 04:10
The response is an object derived from class `requests.models.Response`, makes sense, no? — Nir Alfasi, Nov 09 '17 at 04:12
`r` is of type `requests.models.Response`... what is your question? — juanpa.arrivillaga, Nov 09 '17 at 05:03
@jing a (class) object *is* an instance (of a class). These terms express the same thing — Nir Alfasi, Nov 09 '17 at 16:38

You're getting a Response object after you fire off the request. To get data from the response object you need to access the property you're after, e.g. r.status_code, r.text, etc.

See this documentation for more details.

It is response from HTTP request. If this is a REST API that you are making a call to, you can convert the response to JSON by calling r.json().
