Self reference in Python - Mini Project: Build & Apply

Self Reference in Python

📖 Scenario: Imagine you are creating a simple program to represent a person who can introduce themselves by name.

🎯 Goal: You will build a small program where a variable refers to itself to print a self-introduction message.

📋 What You'll Learn

Create a variable with a person's name

Create a variable that holds a message referencing the name variable

Use self reference to build the message

Print the final self-introduction message

💡 Why This Matters

🌍 Real World

Self reference is useful when you want to build messages or data that depend on existing variables, like user profiles or personalized greetings.

💼 Career

Understanding how variables can refer to themselves or be used inside functions is a basic skill for programming jobs involving data handling and user interaction.

1

Create a variable with the name

Create a variable called name and set it to the string "Alice".

Python

# Create a variable called name and set it to "Alice"
# Your code here

Need a hint?

Use the equals sign = to assign the string "Alice" to the variable name.

2

Create a self-reference message

Create a variable called message that uses the variable name to build the string "Hello, my name is Alice." using an f-string.

Python

name = "Alice"
# Create a variable called message using an f-string that includes name
# Your code here

Need a hint?

Use an f-string like f"Hello, my name is {name}." to include the variable name inside the string.

3

Use self reference in a function

Define a function called introduce that takes no parameters and returns the message variable. Use the message variable inside the function to refer to the self-introduction message.

Python

name = "Alice"
message = f"Hello, my name is {name}."
# Define a function called introduce that returns message
# Your code here

Need a hint?

Define the function with def introduce(): and return the variable message inside it.

4

Print the self-introduction message

Call the function introduce() and print its return value.

Python

name = "Alice"
message = f"Hello, my name is {name}."

def introduce():
    return message

# Call introduce() and print the result
# Your code here

Need a hint?

Use print(introduce()) to show the message on the screen.
