[Solved] Consider this code snippet:from scipy.optimize import dual_annealing def f(x): return (x[0] - 4)**2 result = dual_annealing(f, bounds=[(0, 5)]) print(result.x[1])What error will this code produce? | SciPy

SciPy - Advanced Optimization

Consider this code snippet:

from scipy.optimize import dual_annealing

def f(x):
    return (x[0] - 4)**2

result = dual_annealing(f, bounds=[(0, 5)])
print(result.x[1])

What error will this code produce?

AIndexError because result.x has only one element

BTypeError due to incorrect function definition

CValueError because bounds are invalid

DNo error; code runs successfully

Step-by-Step Solution

Solution:

Step 1: Check function input dimension
The function f takes a 1D input vector with one element.
Step 2: Check bounds
Bounds specify one variable: [(0,5)].
Step 3: Inspect result.x
result.x will be a 1-element array.
Step 4: Accessing result.x[1]
Accessing result.x[1] causes an IndexError because index 1 is out of range.
Final Answer:
IndexError because result.x has only one element -> Option A
Quick Check:
Indexing beyond array length [OK]

Quick Trick: Check array length before indexing [OK]
