--description--

Given the current temperature of a room in Fahrenheit and a target temperature in Celsius, return a string indicating how to adjust the room temperature based on these constraints:

• Return "Heat: X degrees Fahrenheit" if the current temperature is below the target. With X being the number of degrees in Fahrenheit to heat the room to reach the target, rounded to 1 decimal place.
• Return "Cool: X degrees Fahrenheit" if the current temperature is above the target. With X being the number of degrees in Fahrenheit to cool the room to reach the target, rounded to 1 decimal place.
• Return "Hold" if the current temperature is equal to the target.

To convert Celsius to Fahrenheit, multiply the Celsius temperature by 1.8 and add 32 to the result (F = (C * 1.8) + 32).

--hints--

adjust_thermostat(32, 0) should return "Hold".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(adjust_thermostat(32, 0), "Hold")`)
}})

adjust_thermostat(70, 25) should return "Heat: 7.0 degrees Fahrenheit".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(adjust_thermostat(70, 25), "Heat: 7.0 degrees Fahrenheit")`)
}})

adjust_thermostat(72, 18) should return "Cool: 7.6 degrees Fahrenheit".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(adjust_thermostat(72, 18), "Cool: 7.6 degrees Fahrenheit")`)
}})

adjust_thermostat(212, 100) should return "Hold".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(adjust_thermostat(212, 100), "Hold")`)
}})

adjust_thermostat(59, 22) should return "Heat: 12.6 degrees Fahrenheit".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(adjust_thermostat(59, 22), "Heat: 12.6 degrees Fahrenheit")`)
}})

def adjust_thermostat(current_f, target_c):
    target_f = (target_c * 1.8) + 32
    diff = round(abs(target_f - current_f), 1)

    if current_f < target_f:
        return f"Heat: {diff} degrees Fahrenheit"
    elif current_f > target_f:
        return f"Cool: {diff} degrees Fahrenheit"
    else:
        return "Hold"
