-List Slicing in Python-

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 favorite avengers in the order of preference.

Note: Below slicing will work only if the original list contains 9 elements

Creating a list of favorite avengers from it and print it. (assuming the first 3 are the most favorites)

Creating another list of avengers who are less favorite than the above. (assuming the middle 3)

Create a list of least favorite avengers (last 3)

Creating a list containing every second avenger from the main list.

Printing the main avenger's list in reverse ie from least favorite to most favorite.

- 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 Using text: We can also add text to the pygame, to a

- Functions in Python -

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> --------

- 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 each question from the quiz dictionary a. Ask the question
