Hack 1

Python

# Assigning integer `age`
age = 299139

# Assigning boolean `is_old`
is_old = age > 139913

# If the age is over 139913, the first code will be run. Otherwise, the second code will be run.
if is_old:
    print("How are you alive?")
else:
    print("Hi! You can be alive.")

How are you alive?

JavaScript

%%javascript

// Assigning integer `age`
let age = 299139;

// Assigning boolean `is_old`
let is_old = age > 139913;

// If the age is over 139913, the first code will be run. Otherwise, the second code will be run.
if (is_old) {
    console.log("How are you alive?");
} else {
    print("Hi! You can be alive.");
}

Hack 2

Python

# Assigning integer `height_inches`
height_inches = 75

# Average height is between 8 feet and 10 feet, exclusive
is_average_height = height_inches > 96 and height_inches < 120

# Non-average height is anywhere not in that range
is_not_average_height = not is_average_height

# If the height falls in the average range, first code will be run. Otherwise, second code will be run.
if is_average_height:
    print("Your height is average.")
elif is_not_average_height:
    print("You are too tall or too short.")

You are too tall or too short.

JavaScript

%%javascript

// Assigning integer `height_inches`
let height_inches = 75;

// Average height is between 8 feet and 10 feet, exclusive
let is_average_height = height_inches > 96 && height_inches < 120;

// Non-average height is anywhere not in that range
let is_not_average_height = !is_average_height;

// If the height falls in the average range, first code will be run. Otherwise, second code will be run.
if (is_average_height) {
    console.log("Your height is average.");
} else if (is_not_average_height){
    console.log("You are too tall or too short.");
}

Hack 3

Python

# Assigning integer `age`
age = 10

# Only children under the age of 16 may drive
can_drive = age < 16

# If age < 16, first string is printed. Otherwise, second string is printed.
print(can_drive if "You can drive!" else "No driving you old person.")

True

JavaScript

%%javascript

// Assigning integer `age``
let age = 10;

// Only children under the age of 16 may drive
let can_drive = age < 16;

// If age < 16, first string is printed. Otherwise, second string is printed.
console.log(can_drive ? "You can drive!" : "No driving you old person.");
