Q1. Conditional Statements: if, elif, and else Conditional statements allow a program to make decisions and execute different blocks of code based on whether certain conditions are true or false. if statement: This is the primary conditional statement. The code block indented below if executes only if its condition evaluates to True. elif statement: Short for "else if," elif is used to check an additional condition if the preceding if (or elif) condition(s) were False. You can have multiple elif statements. else statement: This block of code executes if all preceding if and elif conditions in the structure evaluate to False. It acts as a default case. Python decides which block of code to execute by evaluating the conditions sequentially from top to bottom. The first condition that evaluates to True will have its corresponding code block executed, and the rest of the if-elif-else structure is then skipped. If no if or elif condition is True, the else block (if present) is executed. Q2. Logical Operators: and, or, not Logical operators are used to combine or modify Boolean expressions, allowing for more complex conditions. and operator: Returns True if both* conditions it connects are True. Otherwise, it returns False. or operator: Returns True if at least one* of the conditions it connects is True. It returns False only if both conditions are False. not operator: Reverses the Boolean value of a condition. If a condition is True, not makes it False, and vice-versa. Q3. Nested Conditional Statements and Nested Logical Operators Nested Conditional Statements: These occur when one if, elif, or else statement is placed inside another. This allows for more granular decision-making, where an outer condition must be met before an inner condition is even considered. Nested Logical Operators: This refers to using logical operators within the conditions of nested if/elif/else statements, or combining multiple logical operators in a single complex condition. Here is the Python program demonstrating all the requirements: `python Q1: Ask for age and determine program eligibility try: age = int(input("Please enter your age: ")) if age < 18: print("You are eligible for the Teen Fitness Program.") program_type = "Teen" elif 18 <= age <= 40: print("You are eligible for the Regular Fitness Program.") program_type = "Regular" else: print("You are eligible for the Senior Wellness Program.") program_type = "Senior" Q2: Ask about medical conditions and use logical operators medical_condition_input = input("Do you have any medical conditions? (yes/no): ").lower() medical_condition = None Initialize to handle invalid input if medical_condition_input == 'yes': medical_condition = True elif medical_condition_input == 'no': medical_condition = False else: print("Invalid input. Please enter 'yes' or 'no'.") Exit or handle invalid input more robustly in a real application medical_condition = None Ensure it's clearly invalid if medical_condition is not None: Only proceed if medical_condition is valid if age >= 40 and medical_condition: print("Medical clearance required before joining.") elif age < 40 or not medical_condition: 'not medical_condition' is equivalent to medical_condition == False print("You can proceed with registration.") Q3: Implement Nested Conditional statements and Nested logical operators membership_type = input("Choose a membership type (Basic/Premium): ").lower() if membership_type == 'basic': personal_training_input = input("Do you want personal training? (yes/no): ").lower() personal_training = None if personal_training_input == 'yes': personal_training = True print("Basic plan with personal training: 45 per month.") elif personal_training_input == 'no': personal_training = False print("Basic plan: 30 per month.") else: print("Invalid input for personal training. Please enter 'yes' or 'no'.") personal_training = None Mark as invalid elif membership_type == 'premium': print("Premium plan: 60 per month.") personal_training = False Not applicable for premium in this logic, or assume no personal training else: print("Invalid membership type. Please choose 'Basic' or 'Premium'.") membership_type = None Mark as invalid Nested Conditionals with logical operators if membership_type == 'premium' and age < 30: print("You qualify for a youth discount! 10% off your plan.") if membership_type == 'basic' and personal_training is not None and not personal_training: print("Consider upgrading to Premium for more benefits!") if medical_condition and membership_type == 'premium': print("We recommend a free consultation before starting.") except ValueError: print("Invalid age input. Please enter a number.") ` Example Output: ` Please enter your age: 25 You are eligible for the Regular Fitness Program. Do you have any medical conditions? (yes/no): no You can proceed with registration. Choose a membership type (Basic/Premium): basic Do you want personal training? (yes/no): no Basic plan: 30 per month. Consider upgrading to Premium for more benefits! ` ` Please enter your age: 45 You are eligible for the Senior Wellness Program. Do you have any medical conditions? (yes/no): yes Medical clearance required before joining. Choose a membership type (Basic/Premium): premium Premium plan: 60 per month. We recommend a free consultation before starting. ` ` Please enter your age: 22 You are eligible for the Regular Fitness Program. Do you have any medical conditions? (yes/no): no You can proceed with registration. Choose a membership type (Basic/Premium): premium Premium plan: 60 per month.
