easy🧠 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Correct usage of pytest.approx
The standard syntax isassert value == pytest.approx(expected).Step 2: Check options
assert output == pytest.approx(2.718) uses the correct syntax. assert pytest.approx(output) == 2.718 reverses the order, which is allowed but less common. assert output == approx(2.718, abs=0.01) usesapproxwithout import. assert output == pytest.approx(2.718, tol=0.01) uses an invalid parametertol.Final Answer:
assert output == pytest.approx(2.718) -> Option BQuick Check:
Standard syntax is value == pytest.approx(expected) [OK]
Quick Trick: Use assert value == pytest.approx(expected) [OK]
Common Mistakes:
MISTAKES- Using incorrect parameter names like 'tol'
- Reversing the order without import
- Using approx without importing it
