 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

 Requests supports the following http request types.
 <code python>
-my_site = "http://www.mysite.org/"
+my_site = "http://httpbin.org/"
 # GET
-response = request.get(my_site)
+response = requests.get(my_site + "get")
 # POST
-response = request.post(my_site)
+response = requests.post(my_site + "post")
 # PUT
-response = request.put(my_site)
+response = requests.put(my_site + "put")
 # DELETE
-response = request.delete(my_site)
+response = requests.delete(my_site + "delete")
+##-- head and options responses are not implemented in the httpbin.org website --##
 # HEAD
-response = request.head(my_site)
+response = requests.head(my_site)
 # OPTIONS
-response = request.options(my_site)
+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'])
+print("Comic Image URL: " + data['img'])
+</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: Pie Charts
+Comic Text: If you can't get your graphing tool to do the shading, just add some clip art of cosmologists discussing the unusual curvature of space in the area.
+Comic Date: 2018-8-10
+Comic Image URL: https://imgs.xkcd.com/comics/pie_charts.png
+</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>
