Popcorn #1

temperature = 80

#Boolean expression:
cold = temperature < 65

#Output:
if cold:
  print("It's cold")

else:
  print("It's not cold")

let temperature = 42;

// Boolean expression:
let cold = temperature < 65;

// Output:
if (cold) {
    console.log("It's cold");
} else {
    console.log("It's not cold");
}

Popcorn Hack #2

let temperature = 100;

// Boolean expressions
let comfortable = temperature < 83 && temperature > 63;
let notComfortable = temperature < 63 || temperature > 83;

if (comfortable) {
    console.log("It is a comfortable temperature");
} else if (notComfortable) {
    console.log("It is not a comfortable temperature");
}

## Example 1: Temperature Check
temperature = 43 

# Boolean expressions
comfortable = temperature < 83 and temperature > 63
not_comfortable = temperature < 63 or temperature > 83

if comfortable: 
    print("It is a comfortable temperature")
elif not_comfortable:
    print("It is not a comfortable temperature")

Popcorn Hack #3

// Define user status
let isAuthorized = True;  // Changed to true

// Use NOT to determine access
let canEnter = !isAuthorized;

// Output the result
console.log(canEnter ? "Access granted!" : "Access denied!");

# Define user status
is_authorized = True  # Changed to true

# Use NOT to determine access
can_enter = not is_authorized

# Output the result
print("Access granted!" if can_enter else "Access denied!")
