The command that is used to copy an object in python includes:
• copy.copy() function: This makes a copy of the file from source to destination. It returns a shallow copy of the parameter that is passed.
• copy.deepcopy(): This also creates a copy of the object from source to destination. It returns a deep copy of the parameter that is passed to the function.
The dictionary consists of all the objects and the copy() method which is used as:
newdict = olddict.copy()

repr() returns a machine-readable representation of values, suitable for an exec command.
Following code sniipets shows working of repr() & str() :

Ques:- What are promises and async await in JavaScript
Right Answer:
Promises in JavaScript are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value. They allow you to handle asynchronous code more easily by providing methods like `.then()` for success and `.catch()` for errors.

`async` and `await` are syntactic sugar built on top of promises. An `async` function always returns a promise, and within an `async` function, you can use `await` to pause execution until a promise is resolved, making the code easier to read and write as if it were synchronous.

Ques:- What is a single page application SPA
Right Answer:
A Single Page Application (SPA) is a web application that loads a single HTML page and dynamically updates the content as the user interacts with the app, without requiring a full page reload.
Ques:- What is the difference between inline inline block and block elements
Right Answer:
Block elements take up the full width available and start on a new line (e.g., `<div>`, `<h1>`). Inline elements only take up as much width as necessary and do not start on a new line (e.g., `<span>`, `<a>`). Inline-block elements are similar to inline elements but can have width and height set, and they respect margins and padding (e.g., `<img>`, `<button>`).
Ques:- What are cookies sessions and local storage in web development
Right Answer:
Cookies are small pieces of data stored on the user's computer by the web browser while browsing a website, used for tracking and remembering information about the user. Sessions are temporary storage on the server that keeps track of user data across multiple requests during a single visit, typically expiring when the user closes the browser. Local storage is a web storage feature that allows websites to store data in the user's browser persistently, even after the browser is closed, with no expiration time.
