- Ans.
List is mutable, tuple is immutable in Python.
List uses square brackets [], tuple uses parentheses ().
List elements can be changed, added, or removed, tuple elements cannot be changed.
Lists are used for collections of items that may need to be modified, tuples are used for fixed collections of items.
Example: list_example = [1, 2, 3], tuple_example = (4, 5, 6)
- Q2. What is namespace and its types?
- Ans.
Namespace is a way to organize variables and functions in a program to avoid naming conflicts.
Namespace helps in avoiding naming conflicts by providing a unique space for each identifier.
Types of namespaces include global namespace, local namespace, built-in namespace, and module namespace.
Example: In Python, each module has its own namespace where all the variables and functions defined in that module reside.

Tuples can be used as keys in dictionaries
- Q2. What are dict comprehension
- Ans.
Dict comprehension is a concise way to create dictionaries in Python using a single line of code.
Dict comprehension uses curly braces {} to create a dictionary with key-value pairs.
It can include conditions and loops to filter or modify the elements being added to the dictionary.
Example: {key: value for key, value in iterable if condition}
