-====== Requests ======
-**General Information**
-The requests library is a http library that allows you to interact with web servers via Python.
-\\
-Sites to Practice Using Requests Against:
-  * Generic http request and response server: http://httpbin.org/
-  * XKCD Comics: https://xkcd.com/json.html
-\\
-**Checklist**
-  * Python 2 or 3
-----
-====== Install ======
-Requests can be installed via pip
-<code bash>
-pip install requests
-</code>
-----
-====== Import ======
-<code python>
-import requests
-</code>
-----
-====== Using Requests ======
-Requests supports the following http request types.
-<code python>
-my_site = "http://httpbin.org/"
-# GET
-response = requests.get(my_site + "get")
-# POST
-response = requests.post(my_site + "post")
-# PUT
-response = requests.put(my_site + "put")
-# DELETE
-response = requests.delete(my_site + "delete")
-##-- head and options responses are not implemented in the httpbin.org website --##
-# HEAD
-response = requests.head(my_site)
-# OPTIONS
-response = requests.options(my_site)
-</code>
-----
-===== GET =====
-Using the GET request and handling the response data.
-\\
-Example: Retrieve the latest XKCD Comic Info ( More Info: https://xkcd.com/json.html)
-<code python>
-#!/usr/bin/python3
-import requests
-# XKCD Current Comic JSON API
-my_site = "https://xkcd.com/info.0.json"
-# Retrieve using GET
-print("Sending GET to: " + my_site)
-response = requests.get(my_site)
-# Extract the JSON object from the response
-data = response.json()
-# Show http status code on GET
-print("Status code is:" + str(response.status_code))
-# Show Certain fields from the JSON object
-print("\n-- The Current XKCD Comic --")
-print("Comic Title: " + data['title'])
-print("Comic Text: " + data['alt'])
-print("Comic Date: " + data['year'] + "-" + data['month'] + "-" + data['day'])
-</code>
-\\
-Output from above example
-<code bash>
-Sending GET to: https://xkcd.com/info.0.json
-Status code is:200
--- The Current XKCD Comic --
-Comic Title: Complex Numbers
-Comic Text: I'm trying to prove that mathematics forms a meta-abelian group, which would finally confirm my suspicions that algebreic geometry and geometric algebra are the same thing.
-Comic Date: 2018-8-3
-</code>
-----
-===== POST =====
-Send data in a POST request.
-\\
-Example: Use the httpbin.org site to delay 5 seconds (will replace with a more interesting example later)
-<code bash>
-#!/usr/bin/python
-import requests
-# Post the request (this will delay/sleep for 5 seconds)
-response = requests.post("http://httpbin.org/delay/5")
-# Extract the JSON object from the response
-data = response.json()
-# Show http status code
-print("Status code is:" + str(response.status_code))
-print("Returned response is:")
-print(data)
-</code>
