--description--

Given the number of Calories burned during a workout, and the number of watt-hours used by your electronic devices during that workout, determine which one used more energy.

To compare them, convert both values to joules using the following conversions:

• 1 Calorie equals 4184 joules.
• 1 watt-hour equals 3600 joules.

Return:

• "Workout" if the workout used more energy.
• "Devices" if the device used more energy.
• "Equal" if both used the same amount of energy.

--hints--

compare_energy(250, 50) should return "Workout".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(compare_energy(250, 50), "Workout")`)
}})

compare_energy(100, 200) should return "Devices".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(compare_energy(100, 200), "Devices")`)
}})

compare_energy(450, 523) should return "Equal".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(compare_energy(450, 523), "Equal")`)
}})

compare_energy(300, 75) should return "Workout".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(compare_energy(300, 75), "Workout")`)
}})

compare_energy(200, 250) should return "Devices".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(compare_energy(200, 250), "Devices")`)
}})

compare_energy(900, 1046) should return "Equal".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(compare_energy(900, 1046), "Equal")`)
}})
