Python for kids and beginners with example code in fun and unique way.

In OOP, we can represent an entity using a class.  A class bundles data (features/properties of entity - color, height, width) and functionality (movement, expression) together.  An instance of a class is known as an object.  Which is the only cartoon series that had predicted that Trump would be elected as the president of the USA and also predicted the coronavirus spread?   Answer: Simpsons.  Simpsons is a very popular animated show. You can build something similar with python.  But have you ever wondered, how Simpsons look the same in all the series? Only his movement looking and, expression change but his main features like color, height, and face look exactly the same all the time.  This is because we create a ‘blueprint’ of Simpsons and whenever we have to simulate him on screen we use this blueprint. This keeps a record of all the features of Simpsons and recreates it whenever we want.  This is where Object-Oriented Programming(OOP) helps us. For eg:  1. You have a class Rectan

  Function-  ● A function is a named block of code designed to perform a specific task.  ● It takes in some input (optional), processes it, and gives us some output. (optional)  ● A function once defined, can be called many times. eg: function to draw a square, function to calculate average, etc. A function has 2 parts - function definition and function call.  Have you ever used a soft drink vending machine?  You give it some input (the drink you want, money ) and it does some processing inside(checks the amount, checks availability) and gives you the output(the soft drink).  Here, you are not bothered about, how the machine works or from where it gets the soft drink. right? You just give the input and you get the required output. isn’t it?  Functions in programming also behave in a similar way. Function definition: Set of instructions that form the function.  Syntax  def  <function name>(<parameter>):        <statement 1>         <statement 2>        --------  

 Game Overview  ● Questions are stored in a file. We will have to read it from the file and store it in a dictionary.  ● 2 points for the correct answer and -1 point for the wrong answer  ● Max no. of questions asked:5  ● Questions will be shuffled once and then asked sequentially.  File Template (for the program)  Each question in the file is stored as <Question> : <Answer> Here ‘:’ acts as a separator between question and answer.  Each line read from the file will be of string data type. ‘:’ helps in separating the answer from the question.  Note: Make sure you add a ‘:’ between question and answer if adding a question manually.  Algorithm  Now that you have seen how the quiz game works, Let's have look at the algorithm for the same.  1. Read the entire file  2. From each line read, get the question and answer a. Add to dictionary  3. Print the rules of the game 4. Shuffle the questions  5. Get each question from the quiz dictionary           a. Ask the question     

  Tuple  A tuple is a collection of objects, ordered and immutable.  EX: What all details are required to create an address?  ● House Number  ● Apartment /Area  ● Street Name  ● Place  ● Pin code  ● District  So for storing an address, will it be easy if we have to create separate variables for each of these parameters?  Tuples help us in such cases.  address= “12/1 “, “Rose Garden”, “The Mall”, “Rauria”,” Jorhat”  Here the parameters separated by commas (,) are considered as a tuple and assigned to a variable. Why ordered?  It is indexed and can be iterated sequentially (same as the list).  Immutable  Tuples once created, cannot be changed.  eg: address= “12/1 “, “Rose Garden”, “The Mall”, “Rauria”,” Jorhat”  address=( “12/1 “, “Rose Garden”, “The Mall”, “Rauria”,” Jorhat”)  Here, both are tuples. () are optional in creating a tuple. Objects separated by commas form a tuple.  Note: Tuples are sequences, just like lists. indexing, slicing, and functions are common for lists and tuples.

 List Slicing : Slicing helps in creating a new list from an existing list.  Syntax list_name [start :end:step] Suppose you have a list of Avengers, arranged in the order of your preference.   avengers=[“Iron Man”,”Thor”,”Hulk”,”Spider Man”,”Captain America”,”Black Panther”,”Hawk Eye”,”Vision”,”Black Widow”] Later you decide to split them into a separate list like  favourite=[“Iron Man”,”Thor”,”Hulk”]                                                   less_favourite =[”Spider Man”,”Captain America”,”Black Panther”]                             least_favourite=[”Hawk Eye”,”Vision”,”Black Widow”]  Now, we have 3 lists formed from the main list. Would you want to create these lists again from the beginning? This is where list slicing helps us. Here is the code to  Get the last few elements of a list. code to Get the first few elements of a list. code to Get the numbers within a range. code to Get elements within a range using the step. code to Get the reverse list. Creating the list of our
