Applying Conditional Logics for Operators

Business Scenario

Welcome!

Today is your fifth day as a Junior Data Analyst at the Indian Railways Reservation Department. Previously you learned how to use conditional statements

Today, your manager wants you to apply multiple conditions together before confirming reservations and allocating seats to verify eligibility and automate confirmation

Pre-Lab Preparation

To complete this task successfully, using Python you must :

Verify passenger eligibility
Apply reservation rules
Check multiple conditions together
Automate ticket confirmation decisions

git pull origin branchName

Git Pull

Topic: Apply Conditional Logics

1) Use Logical Operators

Task 1: Using AND Operator

Create variables for passenger details

passenger_age = 25
ticket_confirmed = True

Apply AND logical operator

if passenger_age >= 18 and ticket_confirmed:
   print("Passenger Eligible for Travel")

Task 2: Using OR Operator

Create seat availability variables

Output

Apply OR logical operator

confirmed_seat = False
rac_seat = True

if confirmed_seat or rac_seat:
   print("Reservation Available")

Task 3: Using NOT Operator

Create cancellation status variable

ticket_cancelled = False

Output

Apply NOT logical operator

if not ticket_cancelled:
   print("Ticket is Active")

Task 4: Apply Reservation Rules for Senior Citizens

Create passenger details

passenger_age = 65
payment_completed = True

Output

Apply reservation condition

if passenger_age >= 60 and payment_completed:
   print("Senior Citizen Reservation Approved")

Task 6: Build Ticket Confirmation System

Output

Create reservation details

available_seats = 5
payment_status = True

Apply confirmation logic

if available_seats > 0 and payment_status:
   print("Ticket Confirmed Successfully")
else:
   print("Reservation Failed")

Output

Create Passenger Details

Task 6: Check Passenger Eligibility for Tatkal Booking

valid_id_proof = True
booking_time_valid = True

Apply Tatkal booking conditions

if valid_id_proof and booking_time_valid:
   print("Tatkal Booking Allowed")
else:
   print("Tatkal Booking Denied")

Output

Create Reservation Details

Task 7: Build Final Reservation Rule Validation Module

passenger_name = "Rahul Sharma"
passenger_age = 30
available_seats = 2
payment_completed = True
ticket_cancelled = False

Apply final reservation validation

if (
   passenger_age >= 18 and
   available_seats > 0 and
   payment_completed and
   not ticket_cancelled
):
   print("===================================")
   print(" Indian Railways Reservation ")
   print("===================================")
   print("Passenger Name :", passenger_name)
   print("Reservation Status : Confirmed")
else:
   print("Reservation Failed")

Output

Save File as : reservation.ipynb

Great job!

You have successfully applied AND, OR, and NOT operators to verify passenger eligibility and seat availability and Enhanced the Reservation System by automating reservation rule checking
