-List in Python-

List:

A list is a collection of ordered and changeable objects variable. It stores more than one value in a single variable.

ex: fruits=[“apple”,”banana”,”mango”] ->list of strings

odd_numbers=[1,3,5,7] ->list of numbers

Why is it called collection?

Stores more than one and different values in a single variable

Why ordered?

Each element of the list is assigned an index number and can be iterated sequentially using this index.

ex: print(fruits[0]) will print “apple” print(fruits[-3]) will also print “apple”

Why changeable?

An element at an index can be changed/deleted.

fruits[0]=” orange” will replace apple with orange in the list. d

el fruits[1] will delete bananas from the list

Note: List values need not be of the same datatype [“apple”, i 2] is also a list

Note: Operations on the list are almost similar to that of strings.

code for above mentioned operations.

So now, we are ready to write some to fun codes with lists. we'll create a bowl of fruit_salad.

Create an empty list of fruit_salad, a list of fruits, and a list of additives.

Print the fruits and additives available .

Add the fruits to the fruit salad.

Now ask your family members, for an additive of their choice, and add it to the fruit salad.

- Object Oriented Programming -

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) h...

- Animating characters using pygame -

If you see closely you can see that the mickey mouse animation is made out of a lot of shapes. But to create something like this we need to make a very complex code. The other way around it is to use an image, other than the basic shapes, pygame also can show images. Using images : Steps to use images in my game: > find the image you want to use > move it to the directory where you have created your code > import/load image To load the image we will first create an object and then use the image. load method to add the image to the object. here, we have created an object called an image. We then use the "pygame.image.load" to find the file in the directory ocean.png has to be replaced with the filename of your file. To place the object on a particular point of the screen we use the blit function. this function means that we are going to add the image onto the screen at position 0,0 mickey mouse is winking Usi...

- Quiz game in Python -

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 eac...
