# --description--
|
|
|
|
Today is Groundhog Day, in which a groundhog predicts the weather based on whether or not it sees its shadow.
|
|
|
|
Given a value representing the groundhog's appearance, return the correct prediction:
|
|
|
|
- If the given value is the boolean `true` (the groundhog saw its shadow), return `"Looks like we'll have six more weeks of winter."`.
|
|
- If the value is the boolean `false` (the groundhog did not see its shadow), return `"It's going to be an early spring."`.
|
|
- If the value is anything else (the groundhog did not show up), return `"No prediction this year."`.
|
|
|
|
# --hints--
|
|
|
|
`groundhog_day_prediction(True)` should return `"Looks like we'll have six more weeks of winter."`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(groundhog_day_prediction(True), "Looks like we'll have six more weeks of winter.")`)
|
|
}})
|
|
```
|
|
|
|
`groundhog_day_prediction(False)` should return `"It's going to be an early spring."`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(groundhog_day_prediction(False), "It's going to be an early spring.")`)
|
|
}})
|
|
```
|
|
|
|
`groundhog_day_prediction(None)` should return `"No prediction this year."`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(groundhog_day_prediction(None), "No prediction this year.")`)
|
|
}})
|
|
```
|
|
|
|
`groundhog_day_prediction(" ")` should return `"No prediction this year."`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(groundhog_day_prediction(" "), "No prediction this year.")`)
|
|
}})
|
|
```
|
|
|
|
`groundhog_day_prediction("True")` should return `"No prediction this year."`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(groundhog_day_prediction("True"), "No prediction this year.")`)
