Chapter 1: Python Basics
Q1: What is Python? Why is it so popular?
, Answer: Python is a high-level, interpreted programming language known for its simplicity and
readability. It's popular because of its clear syntax, dynamic typing, and strong support for multiple
programming paradigms.
Q2: How do you check the Python version you are using?
Answer: You can check the version of Python by running:
python
Copy code
import sys
print(sys.version)
Q3: What are Python's key features?
Answer:
Interpreted Language: No need for compilation.
Dynamically Typed: No need to declare the type of a variable.
Object-Oriented: Supports encapsulation, inheritance, and polymorphism.
Extensive Libraries: Includes standard libraries for a variety of tasks.
Community Support: Vast community and resources for learning and development.
Chapter 2: Data Types and Operations
Q1: What are mutable and immutable data types in Python?
Answer:
Mutable Data Types: Can be changed after creation (e.g., lists, dictionaries, sets).
Immutable Data Types: Cannot be changed after creation (e.g., tuples, strings).
Q2: How can you convert a string to a list in Python?
Answer:
python
Copy code
string = "hello"
string_list = list(string)
print(string_list) # Output: ['h', 'e', 'l', 'l', 'o']
