What will this code print?

import numpy as np
from scipy import integrate
result, error = integrate.quad(lambda x: x**2, 0, 1)
print(round(result, 2))

A0.333

B0.25

C0.33

D0.5

Step-by-Step Solution

Solution:

Step 1: Understand the integral calculation
integrate.quad computes the definite integral of x^2 from 0 to 1, which is 1/3 ≈ 0.3333.
Step 2: Check rounding
Rounding 0.3333 to 2 decimals gives 0.33 (D). A is 0.333 (unrounded), B 0.25 and C 0.5 are wrong.
Final Answer:
0.33 -> Option C
Quick Check:
Integral of x^2 from 0 to 1 = 0.33 [OK]

Quick Trick: Integral of x^2 from 0 to 1 is 1/3 ≈ 0.33 [OK]
