-Operations on Dictionary in Python-

Think of a few scenarios in which we can use a dictionary?

. So, today we will see how we can use the dictionary to maintain a database of Countries and their capitals.

When we create a database, what are the operations we expect to do on it?

● Insert

● Delete

● Display

● search

Let us see the functions/methods, which help us in doing these.

writes code on IDLE Create a dictionary of countries and their capitals.

Print the countries in the dictionary.

Note: Explain how the use of the list is displaying keys as a normal list

Print the capitals stored in the dictionary.

Note: The use of the list is displaying values as a normal list

Get the capital of India from a dictionary using the get() function.

Create an empty dictionary and start an infinite while loop.

Print the menu to maintain a country-capital repository and get user choice.

Check if the choice entered is 1, the get country, capital as user input , and insert these values into the dictionary.

Check if the choice entered is 3 and print all capitals as a list.

Check if the choice entered is 4, get as the user input a country and then print its capital.

Check if the choice entered is 5, get as the user input a country and delete that from the dictionary.

If the option entered is none of the above, exit from the program.

- 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...

- 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...
