Definition and Usage
The requests module allows you to send HTTP
requests using Python.
The HTTP request returns a Response Object with all the response data
(content, encoding, status, etc).
Download and Install the Requests Module
Navigate your command line to the location of PIP, and type the following:
C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip install requests

Python Requests
Release v2. 26. 0. (Installation)
Requests is an elegant and simple HTTP library for Python, built for human beings.
Behold, the power of Requests:
>>> r = (”, auth=(‘user’, ‘pass’))
>>> atus_code
200
>>> r. headers[‘content-type’]
‘application/json; charset=utf8’
>>> r. encoding
‘utf-8’
>>>
‘{“type”:”User”… ‘
>>> ()
{‘private_gists’: 419, ‘total_private_repos’: 77,… }
See similar code, sans Requests.
Requests allows you to send HTTP/1. 1 requests extremely easily.
There’s no need to manually add query strings to your
URLs, or to form-encode your POST data. Keep-alive and HTTP connection pooling
are 100% automatic, thanks to urllib3.

How to Install Requests Library in Python | – Agira Technologies
Python web development is preferable for many developers even tough if it is one of the oldest yet leading programming languages. Python thrives to keep up with the latest technological advancements along with its desirable features. One such great feature is its substantial number of easily available libraries. All you need to do is install the libraries, and start importing them at the beginning of your code. Moreover, you can install any number of libraries to your code according to your need.
Installing a library is not that complex as it sounds. So, here is a descriptive tutorial on how to install a requests library in Python.
What is the request library?
A Request library in Python handles the HTTP calls, where it simplifies the way to send the data on HTTP request and handles the same back in response. It eases the ways to carry out the CRUD operation and other HTTP call activities, such as data scraping. There is no restriction with the data it carries, it can carry everything from header to form data, query parameters, multipart files and others.
Request Library – Installation:
Firstly, before starting with the installation process, make sure that Python and pip were installed prior to ‘request’ module installation. To install the ‘requests’ library for Python, we can use any one of the following methods:
Here is the installation procedure for different operating systems.
Linux
$ pip install requests
In Linux, If you require root permission, use ‘sudo’. Alternatively, you can also use pipenv to install requests library, where pipenv is used to automatically manage the packages during the course of installation/uninstallation.
$ pip install pipenv
Windows
The Windows users need to navigate to the Python directory, and then install the request module as follows:
> python -m pip install requests
Mac
For MacOS, install Python through ‘Home Brew’. Thereafter, install pip and request module (which is the same as Linux installation process. )
Usage of Request Library
Once the installation part is over, you can execute the following functions with the help of request library.
Python Installation
To verify that Python installed on the machine, try the below one:
$ python –version
If the version of Python is not returned, refer Python installation process and proceed with ‘request’ module installation process. For Python 3x, use the command python3 rather python.
$ python3 –version
We are using Python 2x in this blog for experimenting the request module installation. So, you can see this python keyword being in use throughout the article.
2. Access to Python Over Terminal
To access Python over command line, simply type python and hit enter to explore the request module (which is priorly installed)
$ python
3. Import Requests Library
Soon after the entry to the python command line, the appropriate module can be accessed through ‘import’ keyword. In our example, we import the request module for experimenting the functionality of the request module.
>>> import requests
4. To Send Request
A list of Http methods like GET, POST, PUT, PATCH, DELETE are accessible through the request module.
In the following example, a simple get request is sent and the corresponding response is recorded as follows:
>>> (”)
The above request will return
5. To Parse Response
A Http status code for a request can be accessed through request module key status_code like 200, 201, 301, 404, 500, 501 etc.,
>>> response = (”)
>>> atus_code
In the above one, a successful response of 200 returned.
Further, response data of the respective request can be parsed in a variety of formats such as content, text or JSON formats.
>>> ntent
This retrieves the content of the web page requested.
>>>
The above code retrieves the response as string based on header content type, explicitly custom encoding can be passed by response. encoding = ‘utf-8’ or whichever the encoding scheme is required.
>>> ()
Here, it returns JSON for a valid response.
Other Frequently Used Http Methods:
Examples of widely used Http methods using request module in Python is as follows:
>>> (”, json={‘python’: {‘library’: ‘requests’}})
>>> (”, json={‘key’:’value’})
>>> cmd + d (to exit)
A key json carries the payload/body of Http call.
Here is the sample code for a little more clarity
This code sample covers quite a few use cases of request module.
# Importing Request module, which was installed prior to
import requests
# Http Methods:
response = (”)
print (atus_code)
response = (”, json={‘python’: {‘library’: ‘requests’}})
print ()
response = (”, json={‘python’: {‘version’: ‘2x’, ‘library’: ‘requests’}})
response = (”, json={‘python’: {‘version’: ‘3x’, ‘library’: ‘requests’}})
# Status Codes:
for url in [”, ”, ”]:
try:
response = (url)
response. raise_for_status() # Raise exception, if applicable
except:
print (‘Error with status code: ‘ + atus_code)
else:
print (‘Request completed successfully’)
Just copy the sample code to “”, then open the terminal and navigate to the directory where “” resides. Now, run the following command.
Therefore, a successful execution of code would result in use case output.

How request module works Python?
Python requests module has several built-in methods to make Http requests to specified URI using GET, POST, PUT, PATCH or HEAD requests. A Http request is meant to either retrieve data from a specified URI or to push data to a server. It works as a request-response protocol between a client and a server.Mar 12, 2020
