# --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"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(adjust_thermostat(32, 0), "Hold")`)
|
|
}})
|
|
```
|
|
|
|
`adjust_thermostat(70, 25)` should return `"Heat: 7.0 degrees Fahrenheit"`.
|
|
|
|
```js
|
|
({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"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(adjust_thermostat(72, 18), "Cool: 7.6 degrees Fahrenheit")`)
|
|
}})
|
|
```
|
|
|
|
`adjust_thermostat(212, 100)` should return `"Hold"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(adjust_thermostat(212, 100), "Hold")`)
|
|
}})
|
|
```
|
|
|
|
`adjust_thermostat(59, 22)` should return `"Heat: 12.6 degrees Fahrenheit"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(adjust_thermostat(59, 22), "Heat: 12.6 degrees Fahrenheit")`)
|
|
}})
