-While Loop in Python-


While loop: 

Allows code to be executed repeatedly, depending on whether a condition is satisfied or not. 

Have you ever watched the movie, ‘Harry Potter’? We are going to have a sneak peek into the magical wizarding world.

 Quidditch is a dangerous but popular sport played by riding on flying broomsticks. In the Quidditch match, the game continues till the time someone catches the Golden Snitch. 


In this game, we can never say beforehand how much time the game continues. It will come to an end depending on only one condition i.e. catching the golden snitch. These kinds of events can be implemented using a while loop that stops only based on some conditions.

Note: 

The loop runs till the time condition is true. When the condition becomes false, we exit the loop. Let’s check out the syntax of the while loop. 

And this is how a finite while loop can be written. It is executed till the time condition becomes false.

Note: 
 ● A counter variable is initialized before the loop
 ● Condition is based on this counter
 ● The counter variable is incremented inside the loop. 

Statements that can alter normal program flow. 
"break" 
This can be used to break from the loop, even if the condition is true. 

Now let's write a program to brew a magic potion. Remember we are dealing with magic ingredients, so all the steps have to be followed accurately. Arrange all the 5 ingredients required for the potion. 



Now take out the exact measurement of the ingredient such that, while brewing it will be all ready to put in. Ingredient 5 - 5 pieces Ingredient 4 - 4 pieces Ingredient 3 - 3 pieces Ingredient 2 - 2 pieces Ingredient 1 - 1 piece














Add the ingredients to the magic pot and start brewing. Ingredients to be added in the order – 
Ingredient 1 - 1 piece 
Ingredient 2 - 2 pieces
Ingredient 3 - 3 pieces 
Ingredient 4 - 4 pieces
Ingredient 5 - 5 pieces



















Keep stirring till the time bubbles are formed.
User input : 0 if no bubble is formed 1 if a bubble is formed 


















Keep the potion to rest. You can start serving it only when the user enters the secret code. The secret code is 444. You can give a clue to the user for the secret code. 









Output:










Serve the magic potion prepared in equal quantities. Get as input quantity and number of people to be served.

- 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...

- For loop in Python -

Loops: Loops are control structures used to repeat a given section of code  ● a certain number of times or  ● until a particular condition is met.  How do we keep ourselves fit nowadays? We must be doing some exercises ..right?   The steps followed in doing the exercise are repeated many times ..isn’t it? Depending on the fitness level of the person, he can choose to repeat a step 10,20, or even 100 times. Now suppose, you want to write a program to simulate exercise steps. Is it feasible to write the same steps again and again? Also, how many times does it has to be repeated changes from person to person. Looping structures come to our rescue in such scenarios. Duplicating lines can be eliminated by repeating them a required number of times. ‘ for’ loop ‘for loops’ are used when you have a block of code that you want to repeat a fixed number of times. A series of numbers within a given range.  Note :  ● A range has 3 parameters -start, end, ste...

-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  G...
