What is JSON? JSON (JavaScript Object Notation) is a compact, text based format for computers to exchange data. The official Internet media type for JSON is application/json, and the JSON filename extension is .json JSON is built on two structures: A collection of name/value pairs An ordered list of values. JSON take these forms: objects, array, value, string, number Parse JSON objects in Python Using the Requests Library in Python Google Command Line Script Object Unordered set of name/value pairs. Begins with { and ends with }. Each name is followed by : (colon) The name/value pairs are separated by , (comma). Array Ordered collection of values. Begins with [ and ends with ]. Values are separated by , (comma). Value Can be a string in double quotes, number, or true or false or null, or an object or an array. String A sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. Number Integer, long, float The following example shows the JSON representation of an object that describes a person: { “firstName”: “John”, “lastName”: “Smith”, “age”: 25, “address”: { “streetAddress”: “21 2nd Street”, “city”: “New York”, “state”: “NY”, “postalCode”: “10021” }, “phoneNumber”: [ { “type”:…

Python comes pre-equipped with a JSON encoder and decoder to make it very simple to play nice with JSON in your applications The simplest way to encode JSON is with a dictionary. This basic dictionary holds random values of various datatypes. data = { a: 0, b: 9.6, c: “Hello World”, d: { a: 4 } } Using the Requests Library in Python CommandLineFu with Python Python Command Line IMDB Scraper We then use json.dumps() to convert the dictionary to a JSON object. import json data = { a: 0, b: 9.6, c: “Hello World”, d: { a: 4 } } json_data = json.dumps(data) print(json_data) This will print out {“c”: “Hello World”, “b”: 9.6, “d”: {“e”: [89, 90]}, “a”: 0} Notice how the keys are not sorted by default, you would have to add the sort_keys=True argument to json.dumps() like so. import json data = { a: 0, b: 9.6, c: “Hello World”, d: { a: 4 } } json_data = json.dumps(data, sort_keys=True) print(json_data) Which would then output the sorted keys. {“a”: 0, “b”: 9.6, “c”: “Hello World”, “d”: {“e”: [89, 90]}}

Overview Request to an HTTP API is often just the URL with some query parameters. API Response The responses that we get from an API are data, that data can come in various formats, with the most popular being XML and JSON. Many HTTP APIs support multiple response formats so that developers can choose the one they’re more comfortable parsing. CommandLineFu with Python How to use the Vimeo API in Python Extracting YouTube Data With Python Using API Getting Started To get started, lets create a simple data structure and put in some data. First we import the json module into our program. import json # Create a data structure data = [ { ‘Hola’:’Hello’, ‘Hoi’:”Hello”, ‘noun’:”hello” } ] To print the data to screen, is as simple as: print ‘DATA:’, (data) When we print the Data as above, we will see the following output: DATA: [{‘noun’: ‘hello’, ‘Hola’: ‘Hello’, ‘Hoi’: ‘Hello’}] JSON Functions When you use JSON in Python, there are different function that we can make use of Json Dumps The json.dumps function takes a Python data structure and returns it as a JSON string. json_encoded = json.dumps(data) # print to screen print json_encoded OUTPUT: [{“noun”: “hello”, “Hola”:…

Overview In this post, we will explain how you can parse JSON objects in Python. Knowing how to parse JSON objects is useful when you want to access an API from various web services that give the response in JSON. Getting Started First thing you have to do, is to find an URL to call the API. In my example, I will use the Twitter API. Start with importing the modules that we need for the program. import json import urllib2 Open the URL and the screen name. url = “http://api.twitter.com/1/statuses/user_timeline.json?screen_name=wordpress” Print out the result print data Google Command Line Script CommandLineFu with Python Extracting YouTube Data With Python Using API Using the Twitter API to parse data This is a very simple program, just to give you an idea of how it works. #Importing modules import json import urllib2 # Open the URL and the screen name url = “http://api.twitter.com/1/statuses/user_timeline.json?screen_name=wordpress” # This takes a python object and dumps it to a string which is a JSON representation of that object data = json.load(urllib2.urlopen(url)) #print the result print data If you are interested to see another example of how to use JSON in Python, please have a look at the “IMDB…

Python Programming – Introduction to Selenium Software testing refers to a set of processes and procedures which help us identify whether the product at hand is getting built as per expectation or not. If we find any deviations we log them as defects, and in the subsequent releases we perform regression testing, retest the bugs, and eventually, we are able to release a build to the market with an acceptable bug list. These regression tests, which we have to perform with every release cycle, are mandatory as well as monotonous in nature, which makes them an ideal candidate for test automation. There are many tools available in the market which allows us to automate our web applications, both commercial and open source. We have tools like UFT, RFT, Silk, Watir, Selenium, and others. Of these, Selenium, which is an open-source functional testing tool for web applications, is the most popular. In this chapter, we will introduce it. Structure History of Selenium Benefits of Selenium Components of Selenium Architecture of Selenium Objective In this chapter, we are going to learn about Selenium as a test automation tool the reason for its popularity. We are also going to learn about the architecture…

Python Programming – Python Operator Overloading In the previous chapter, we learn the fundamentals of OOPS, i.e., the creation of user-defined data type classes and objects in Python. In this chapter, we will learn one of the significant features of object-oriented. programming structures (OOPS) that is operator overloading. As implied from the name, operator overloading means assigning special meaning to the existing operator to perform some intended task. In other words, the same operator exhibiting different meanings as per the situation is called operator overloading. For example, the “+’ operator is used to add two numbers, the same can be used for merging two lists and concatenating two strings. It indicates that the same ‘+’ operator can be used to perform different tasks based on the context in which it is being used. Similarly, two-class objects can also be added by using the concept of operator overloading by using the similar syntax that is used for adding two integer numbers. In the following sections, the concept of operator overloading is discussed in detail. Python Programming – Overloading Operator in Python Alike, the ‘+’ operator overloading, the subtraction operator can also be overloaded. The programming code for the same is given…
