Building Basic Output Programs

Business Scenario

Welcome!

Today is your second day as a Junior Data Analyst at the Indian Railways Reservation Department. In the previous lab, you successfully installed required softwares.

The department requires a basic program capable of displaying train details, passenger information and ticket confirmation messages in a properly formatted manner.

Pre-Lab Preparation

To complete this task successfully, you must understand core Python programming fundamentals such as:

  • Variables and Python Operators

  • Data Types, Identifiers, and Literals

  • Type Casting

  • Comments

Topic : Build Basic Output Programs for Railway System

1) Display welcome message, train details, passenger info
2) Format output using print()
3) Simulate ticket confirmation message

git pull origin branchName

Git Pull

Task 1: Creating Variables for Railway Information

Open Jupyter Notebook.

A Variable in Python is a name used to store data or values in memory, which can be used and changed later in a program.

Declare variables for train and passenger information

2

train_name = "Rajdhani Express"
train_number = 12951
source_station = "Mumbai"
destination_station = "Delhi"
ticket_price = 2450.75

Run the Program

3

The code will be executed and you have successfully created a Variable

Task 2: Displaying Welcome Message and Train Details

1

Use the print() function to display railway system details

Execute the code and observe the output

2

print("Welcome to Indian Railway Reservation System")
print("Train Name :", train_name)
print("Train Number :", train_number)
print("Source Station :", source_station)
print("Destination Station :", destination_station)

You have successfully displayed the welcome message and train details

Task 3: Understanding Data Types and Identifiers

1

Use the type() function to identify data types

print(type(train_name))
print(type(train_number))
print(type(ticket_price))

Create valid identifiers and literals for passenger information.

2

The connection between identifiers and literals is that "identifiers" are used to store or refer to "literal" values in a program

Example:

age = 21

  • age → Identifier

  • 21 → Literal

Here, the identifier age stores the literal value 21.

passenger_name = "Rahul Sharma"
seat_number = "B2-45"
is_confirmed = True

Execute the code, to create an "identifier" and "literal"

3

Task 4: Performing Type Casting

1

Convert float data into integer data type

Convert integer data into string format

2

ticket_price_integer = int(ticket_price)
print(type(ticket_price_integer))
train_number_string = str(train_number)
print(type(train_number_string))

Task 5: Adding Comments in Python Program

1

Add comments for the code

In Python, comments are lines in the code that are used to note, explain or describe the code and ignored while execution

Task 6: Simulating Ticket Confirmation Message

Create passenger confirmation variables

1

passenger_name = "Rahul Sharma"
seat_number = "B2-45"
confirmation_status = "Confirmed"

Display ticket confirmation message using formatted output

2

The final railway ticket output has been generated

Save the file as : railway_output_system.ipynb

Great job!

You have successfully created variables, explored data types, identifiers, literals and type casting concepts. Used comments to improve program readability and documentation.
