NumPy - Fundamentals

You have a list of daily temperatures: [20, 22, 19, 24, 21]. Using NumPy, how can you quickly find the average temperature?

Anp.mean([20, 22, 19, 24, 21])

Bsum([20, 22, 19, 24, 21]) / 5

Cnp.sum([20, 22, 19, 24, 21])

Dlen([20, 22, 19, 24, 21])

Step-by-Step Solution

Solution:

Step 1: Identify NumPy function for average
NumPy provides np.mean() to calculate the average of array elements.
Step 2: Compare with other options
len() counts elements; sum() / 5 calculates average manually without NumPy's dedicated function; np.sum() sums values; np.mean() finds the average quickly.
Final Answer:
np.mean([20, 22, 19, 24, 21]) -> Option A
Quick Check:
Use np.mean() for average [OK]

Quick Trick: Use np.mean() to get average quickly [OK]
