Task
📝 **Task:** Write a function `double(n)` that takes a number and returns it multiplied by 2.
📋 **Steps:**
1. Define `def double(n):`
2. Return `n * 2`
3. Call `double(7)` and `print` the result
💡 **Similar example (different values):**
```python
def triple(x):
return x * 3
print(triple(4)) # 12
```
⚠️ **Hint:** `return` hands the value back, `print` only displays it.
🎯 **Expected output:** `14`
