To collect information required for an AI solution.

Example:

For a study planner AI:

Data collected:

  • Study hours
  • Subjects
  • Test dates
  • Learning preferences

Activity 4: Data Visualization

Students can represent collected data using:

  • Bar charts
  • Line graphs
  • Tables
  • Pie charts

Example:

A graph showing daily study hours.

Python Practical Programs Class 9

Program 1: Display a Message

Objective:

To learn the print function.

print("Welcome to Artificial Intelligence")

Output:

Welcome to Artificial Intelligence

Program 2: Add Two Numbers

Objective:

To understand variables and arithmetic operations.

a = 10
b = 20

sum = a + b

print("Sum =", sum)

Output:

Sum = 30

Program 3: Take Input from User

Objective:

To learn input function.

name = input("Enter your name: ")

print("Hello", name)

Program 4: Find Area of Rectangle

length = 10
breadth = 5

area = length * breadth

print("Area =", area)

Output:

Area = 50

Program 5: Check Even or Odd Number

number = int(input("Enter a number: "))

if number % 2 == 0:
    print("Even Number")
else:
    print("Odd Number")

Program 6: Check Pass or Fail

marks = int(input("Enter marks: "))

if marks >= 33:
    print("Pass")
else:
    print("Fail")

Program 7: Find Largest Number

a = 15
b = 25

if a > b:
    print("a is greater")
else:
    print("b is greater")

Program 8: Print Numbers Using Loop

for i in range(1,6):
    print(i)

Output:

1
2
3
4
5

Program 9: Calculate Sum Using Loop

total = 0

for i in range(1,6):
    total = total + i

print(total)

Output:

15

Program 10: Simple AI Idea Using Python Logic

Example:

A basic recommendation system:

interest = input("Enter your interest: ")

if interest == "AI":
    print("Recommended: Learn Python")
else:
    print("Explore more technology topics")
