Lesson 1: Variables in Python

Introduction

In this assignment, you will learn about variables in Python and how to use them to store and manipulate data.

Tasks

1. Create a Python program that declares three variables: name, age, and country.
2. Assign appropriate values to each variable. For example, name could be your name, age could be your age in years, and country could be your country of residence.
3. Print the values of the variables to the console using the print() function.
4. Write a comment explaining the purpose of each variable.

# Variable Declarations
name    = "John Doe"
age     = 20
country = "Aruba"

# Printing Variable Values
print("Name   :", name)
print("Age    :", age)
print("Country:", country)

Output Output

Name: John Doe
Age: 20
Country: Aruba

In this sample code, three variables are declared: name, age, and country. Appropriate values are assigned to each variable. The print() function is then used to display the values of the variables to the console.

You can copy this code into your Python file and run it to see the output with the assigned values. Feel free to modify the values or add any additional code as needed to test your understanding of variables in Python.

Lesson 2: Functions in Python

Introduction

In this lesson, you will learn how to define and use functions in Python.

Tasks

1. Create a Python program that defines a function called greet() without any parameters.
2. Inside the greet() function, print a greeting message, such as "Hello, welcome to the world of programming!"
3. Call the greet() function outside its definition to execute it.
4. Write a comment explaining the purpose of the greet() function.

In this script, a function called greet() is defined without any parameters. Inside the function, a greeting message is printed to the console. The greet() function is then called outside its definition to execute it and display the greeting message.

You can copy this script into your Python file and run it to see the output. The greeting message will be displayed as "Hello, welcome to the world of programming at AIB!". Feel free to modify the message or add any additional code as needed.

# Function Definition
def greet():
    print("Hello, welcome to the world of programming at AIB!")

# Calling the greet() function
greet()

Output

Hello, welcome to the world of programming at AIB!

Lesson 3: Loops in Python

Introduction

2. Inside the loop, print each number on a separate line.
3. Write a comment explaining the purpose of the for loop.

# List of Numbers
numbers = [1, 2, 3, 4, 5]

# For Loop to Print Numbers
for number in numbers:
    print(number)

Output

1
2
3
4
5

Lesson 4: Working with Lists in Python

Introduction

In this lesson, you will learn how to work with lists in Python, which allow you to store and manipulate multiple values in a single variable.

Tasks

1. Create a Python program that defines a list called fruits containing the names of three fruits.
2. Access and print the second fruit in the list.
3. Add a new fruit to the end of the list.
4. Update the value of the first fruit in the list.
5. Write a comment explaining the purpose of each step.

# List of Fruits
fruits = ["apple", "banana", "orange"]

# Accessing and Printing a Fruit
print("Second Fruit:", fruits[1])

# Adding a New Fruit
fruits.append("grape")

# Updating a Fruit
fruits[0] = "strawberry"

# Printing the Updated List of Fruits
print("Updated Fruits:", fruits)

Output

Second Fruit: banana
Updated Fruits: ['strawberry', 'banana', 'orange', 'grape']

Lesson 5: Conditional Statements in Python

Introduction

In this lesson, you will learn how to use conditional statements in Python to make decisions based on certain conditions.

Tasks

1. Create a Python program that asks the user to enter their age.
2. Store the user's input in a variable.
3. Use an if statement to check if the user is above 18 years old.
4. If the user is above 18, print a message saying they are eligible to vote. Otherwise, print a message saying they are not eligible to vote.
5. Write a comment explaining the purpose of each step.

# User Input
age = int(input("Enter your age: "))

# Eligibility Check
if age >= 18:
    print("You are eligible to vote!")
else:
    print("You are not eligible to vote.")

Output

Enter your age: 22
You are eligible to vote!

Lesson 6: User Input in Python

Introduction

In this lesson, you will learn how to take user input in Python and use it in your programs.

Tasks

1. Create a Python program that asks the user to enter their name.
2. Store the user's input in a variable.
3. Print a personalized greeting message using the user's name.
4. Write a comment explaining the purpose of each step.

# User Input
name = input("Enter your name: ")

# Greeting Message
print("Hello, " + name + "!")

# Note: You can also use f-string formatting for the greeting message
# print(f"Hello, {name}!")

Output

Enter your name: John
Hello, John!

Explanation

In this lesson, we use the input() function to take user input. The input() function prompts the user to enter their name, and the user's input is stored in the name variable. We then print a greeting message using the user's name by concatenating it with a predefined string. You can also use f-string formatting to achieve the same result by placing the variable name within curly braces {} in the print statement.

Assignment 1: Printing a Christmas Tree

Introduction

In this assignment, you will apply your knowledge of variables, functions, and for loops in Python to generate and print a Christmas tree pattern using asterisks and spaces.
