# --description--
Given the snow depth and slope of a mountain, determine if there's an avalanche risk.
- The snow depth values are `"Shallow"`, `"Moderate"`, or `"Deep"`.
- Slope values are `"Gentle"`, `"Steep"`, or `"Very Steep"`.
Return `"Safe"` or `"Risky"` based on this table:
| |`"Shallow"`|`"Moderate"`|`"Deep"`|
|-|-|-|-|
|`"Gentle"`|`"Safe"`|`"Safe"`|`"Safe"`|
|`"Steep"`|`"Safe"`|`"Risky"`|`"Risky"`|
|`"Very Steep"`|`"Safe"`| `"Risky"`|`"Risky"`|
# --hints--
`avalanche_risk("Shallow", "Gentle")` should return `"Safe"`.
```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(avalanche_risk("Shallow", "Gentle"), "Safe")`)
}})
```
`avalanche_risk("Shallow", "Steep")` should return `"Safe"`.
```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(avalanche_risk("Shallow", "Steep"), "Safe")`)
}})
```
`avalanche_risk("Shallow", "Very Steep")` should return `"Safe"`.
```js
