🔹 Section A — Textual Questions and Answers
Q1. What is Python?
Answer:
Python is a high-level, interpreted programming language used for general-purpose programming. It is easy to learn, read, and write because of its simple syntax.
Q2. List any four features of Python programming.

Easy to learn and use
-
Open-source and free
-
Portable and platform independent
-

Q4. What is IDLE in Python?
Answer:

Q5. What is the difference between Python Shell and Script Mode?
Answer:
-
Shell Mode: Executes Python commands one at a time (interactive).
-

Q6. What are Lines and Indentation in Python?
Answer:
In Python, indentation (spaces at the beginning of a line) is used to define code blocks instead of braces {}. Proper indentation is necessary for the code to run correctly.
Q7. What are Identifiers in Python?
Answer:
