1. What is the purpose of the @staticmethod decorator in Python?

   The @staticmethod decorator is used to define a static method in a Python class. A static method is a method that belongs to a class rather than an instance of the class. It can be called without creating an instance of the class, and it cannot access or modify the state of an instance. Static methods are typically used to create utility functions or helper functions that do not depend on the state of an object. For example, consider a class Math with a square method defined as a static method:…

2. What is list comprehension?

   List comprehension is a concise way of creating a new list in Python by transforming or filtering another list.

3. What is the syntax for list comprehension?

   The syntax for list comprehension is: new_list = [expression for item in iterable if condition]

4. What is the expression in list comprehension?

   The expression is what will be performed on each item in the iterable to create the new list.

5. What is the iterable in list comprehension?

   The iterable is the original list that we want to transform or filter to create the new list.

6. What is the condition in list comprehension?

   The condition is an optional filter that can be applied to the iterable. Only the items that satisfy the condition will be included in the new list.

7. What are the benefits of using list comprehension?

   List comprehension is a more concise and efficient way of creating new lists compared to using traditional for-loops. It also makes the code easier to read and understand.
