1# Select this code:
2result = [x**2 for x in range(10) if x % 2 == 0]

5# Copilot: "This is a list comprehension that..."

1/fix The function returns None instead of the expected value

1def get_max(numbers):
2    max_val = numbers[0]
3    for n in numbers:
4        if n > max_val:
5            max_val = n
6    # Bug: forgot to return!
7
8# /fix returns None
9# Copilot adds: return max_val

1/tests Generate unit tests for this function using pytest

1def add(a, b):
2    return a + b
3
4# /tests
5# Copilot generates:
6def test_add_positive():
7    assert add(2, 3) == 5
8
9def test_add_negative():
10    assert add(-1, -1) == -2
