Homework Hack
Python
# Define a dictionary representing a car
car = {'make': 'Tesla', 'model': 'Model 3', 'year': 2020}
# Looping through keys
for key in car:
print(f'Key: {key}, Value: {car[key]}')
# Looping through values
for value in car.values():
print(f'Car Value: {value}')
# Looping through keys and values
for key, value in car.items():
print(f'Car Key: {key}, Car Value: {value}')
Key: make, Value: Tesla
Key: model, Value: Model 3
Key: year, Value: 2020
Car Value: Tesla
Car Value: Model 3
Car Value: 2020
Car Key: make, Car Value: Tesla
Car Key: model, Car Value: Model 3
Car Key: year, Car Value: 2020
JavaScript
%%js
// Define a dictionary representing a phone
let phone = {'brand': 'Apple', 'model': 'iPhone 13', 'year': 2021};
// Looping through keys
for (let key in phone) {
console.log(`Key: ${key}, Value: ${phone[key]}`);
}
// Looping through values
Object.values(phone).forEach(value => {
console.log(`Phone Value: ${value}`);
});
// Looping through keys and values
Object.entries(phone).forEach(([key, value]) => {
console.log(`Phone Key: ${key}, Phone Value: ${value}`);

roll = random.choice(["side 1", "side 2", "side 3", "side 4", "side 5", "side 6"])
print(f"You rolled onto: {roll}")
print("Rolled onto side 1!")
#Rolling a dice until it lands on side 1, I made this myself
You rolled onto: side 2
You rolled onto: side 6
You rolled onto: side 1
Rolled onto side 1!

Index Loops
Popcorn Hack 1 - Python
# List of tasks
tasks = [
"Study for bio",
"Play soccer",
"Finish math homework",
]
# Function to display tasks with indices
def display_tasks():
print("Your To-Do List:")
for index in range(len(tasks)):
print(f"{index + 1}. {tasks[index]}") # Display task with its index
# Call the function
display_tasks()
Your To-Do List:
1. Study for bio
2. study for chem
3. study for math
%%javascript
// List of tasks
const tasks = [
"Study for bio",
"Play soccer",
"Finish math homework",
];
// Function to display tasks with indices
function displayTasks() {
console.log("Your To-Do List:");
for (let index = 0; index < tasks.length; index++) {
console.log(`${index + 1}. ${tasks[index]}`); // Display task with its index
}
}
// Call the function
displayTasks();
<IPython.core.display.Javascript object>
Continue and Break
Popcorn Hack 1
%%javascript
// Custom break logic: stop inner loop when i equals 3 and outer loop when i equals 7
for (let outer = 0; outer < 10; outer++) {
console.log(`Outer loop iteration: ${outer}`);
for (let inner = 0; inner < 10; inner++) {
if (inner === 3) {
console.log("Inner loop break");
break
}
console.log(`Inner loop iteration: ${inner}`);
}
if (outer === 7) {
console.log("Outer loop break");
break
}
}

# Simple continue loop in Python
for i in range(10):
if i == 5:
print("Skipping number 5!")
continue
print(f"Number: {i}")
Number: 0
Number: 1
Number: 2
Number: 3
Number: 4
Skipping number 5!
Number: 6
Number: 7
Number: 8
Number: 9
Homework Hack 1
%%javascript
for (let i = 0; i < 20; i += 2) {
if (i === 10) {
console.log("Breaking the loop at 10!");
break;
}
console.log(i);
}

Homework Hack 2
for i in range(10):
if i == 5:
continue
print(f"This number is {i}")
#as you can see number 5 is skipped because it isn't printed
This number is 0
This number is 1
This number is 2
This number is 3
This number is 4
This number is 6
This number is 7
This number is 8
This number is 9
