Parameters and arguments in Python - Mini Project: Build & Apply

Understanding Parameters and Arguments in Python

📖 Scenario: You are creating a simple program to greet people by their names. You want to practice how to use parameters and arguments in functions to make your greetings flexible.

🎯 Goal: Build a Python program that defines a function with a parameter to accept a name and then calls the function with different names as arguments to print personalized greetings.

📋 What You'll Learn

Define a function called greet with one parameter named name

Inside the function, print a greeting message that includes the name parameter

Call the greet function with the argument "Alice"

Call the greet function with the argument "Bob"

Print the greeting messages exactly as shown in the final output

💡 Why This Matters

🌍 Real World

Functions with parameters and arguments are used everywhere in programming to make code reusable and flexible, like greeting users by name in apps or websites.

💼 Career

Understanding how to define and call functions with parameters is a fundamental skill for any programming job, enabling you to write clean and efficient code.

1

Define the greet function with a name parameter

Write a function called greet that takes one parameter named name. Inside the function, write a print statement that says "Hello, {name}!" using an f-string.

Python

# Define the greet function with parameter name
# Your code here

Need a hint?

Remember to use def to define a function and include name inside the parentheses.

2

Call the greet function with the argument "Alice"

Call the function greet with the argument "Alice" to print a greeting for Alice.

Python

def greet(name):
    print(f"Hello, {name}!")

# Call greet with "Alice"
# Your code here

Need a hint?

Use the function name greet followed by parentheses and the argument "Alice".

3

Call the greet function with the argument "Bob"

Call the function greet again with the argument "Bob" to print a greeting for Bob.

Python

def greet(name):
    print(f"Hello, {name}!")

greet("Alice")

# Call greet with "Bob"
# Your code here

Need a hint?

Repeat the function call with the new argument "Bob".

4

Print the greetings for both Alice and Bob

Run the program to print the greetings for both Alice and Bob. Use print statements inside the greet function only.

Python

def greet(name):
    print(f"Hello, {name}!")

greet("Alice")
greet("Bob")

# Run the program to see the greetings
# Your code here

Need a hint?

Just run the program as it is to see the greetings printed.
