Notes

Booleans:

  • A data type in programming representing true or false values.
  • Used for making logical decisions and comparisons.
  • True: Represents a condition that is considered as “true” or “yes.”
  • False: Represents a condition that is considered as “false” or “no.”

Relational Operators:

  • Equal to: a = b
  • Not equal to: a != b
  • Greater than: a > b
  • Less than: a < b
  • Greater than or equal to: a >= b
  • Less than or equal to: a <= b

Conditionals

  • Condition statements are fundamental in programming. They consist of:
    • Condition: A Boolean expression or logical test.
    • True Block: Code executed if the condition is true.
    • False Block (optional): Code executed if the condition is false.

Homework

# HW 1 - Voting Eligibility
# Get user input for age
age = int(input("Enter your age: "))

# Check eligibility using boolean logic
if age >= 18:
    print("You are eligible to vote.")
else:
    print("You are not eligible to vote.")

# HW 2 - Employee Bonus
# Get user input for salary and years of service
salary = float(input("Enter your salary: "))
years_of service = int(input("Enter your years of service: "))

# Calculate bonus
if years_of_service > 5:
    bonus = 0.05 * salary
    print(f"Your bonus amount is ${bonus:.2f}")
else:
    print("You are not eligible for a bonus.")

# HW 3 - Grading System
# Get user input for marks
marks = float(input("Enter your marks: "))

# Determine the grade based on the grading system
if marks < 25:
    grade = "F"
elif 25 <= marks < 45:
    grade = "E"
elif 45 <= marks < 50:
    grade = "D"
elif 50 <= marks < 60:
    grade = "C"
elif 60 <= marks < 80:
    grade = "B"
else:
    grade = "A"

# Print the corresponding grade
print(f"Your grade is: {grade}")
