Task
📝 **Task:** Write a function `is_even(n)` that returns `True` if the number is even, `False` otherwise.
📋 **Steps:**
1. Define `def is_even(n):`
2. Use the modulo operator: `n % 2 == 0`
3. Return that comparison via `return`
4. Call the function twice: `is_even(4)` and `is_even(7)`
💡 **Similar example (divisibility by 5):**
```python
def divisible_by_5(n):
return n % 5 == 0
print(divisible_by_5(15)) # True
print(divisible_by_5(11)) # False
```
⚠️ **Hint:** `n % 2` is 0 for even, 1 for odd. Compare with 0.
🎯 **Expected output:**
```
True
False
```
