You want to load a .mat file but only need the variable named temperature. How can you load just this variable efficiently using scipy.io?

AUse loadmat('file.mat', variable_names=['temperature'])

BUse loadmat('file.mat')['temperature'] after loading full file

CUse savemat with variable_names argument

DUse loadmat with a filter function

Step-by-Step Solution

Solution:

Step 1: Recall loadmat parameters
loadmat supports a variable_names parameter to load only specified variables.
Step 2: Check options
Use loadmat('file.mat', variable_names=['temperature']) uses this parameter correctly. Use loadmat('file.mat')['temperature'] after loading full file loads full file then extracts variable, less efficient.
Final Answer:
Use loadmat('file.mat', variable_names=['temperature']) -> Option A
Quick Check:
Load specific variables with variable_names param [OK]

Quick Trick: Use variable_names param to load specific vars [OK]
