Learning Objectives

• Understand decision making in Python.
• Use if, elif and else.
• Create simple real-life applications.
• Improve logical thinking.
• Test Python programs independently.

Recap: Conditional Statements

Conditional statements help a program make decisions. Python checks whether a condition is True or False before executing instructions.

if condition:
    statement

elif condition:
    statement

else:
    statement

Mini Application 1

Even or Odd Number Checker

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

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

Mini Application 2

Voting Eligibility Checker

age = int(input("Enter your age: "))

if age >= 18:
    print("Eligible to Vote")
else:
    print("Not Eligible")

Mini Application 3

Positive, Negative or Zero

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

if num > 0:
    print("Positive")

elif num < 0:
    print("Negative")

else:
    print("Zero")

Mini Application 4

Simple Password Checker

password = input("Enter Password: ")

if password == "python123":
    print("Access Granted")

else:
    print("Wrong Password")

Mini Application 5

Grade Calculator

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

if marks >= 90:
    print("Grade A")

elif marks >= 75:
    print("Grade B")

elif marks >= 60:
    print("Grade C")

else:
    print("Needs Improvement")

Comparison Operators Used

Challenge Activity

Design your own Python application using at least:

• ✔ One input
• ✔ One if statement
• ✔ One elif
• ✔ One else

Quick Quiz
