NumPy - Array Data Types

Identify the error in this code snippet:

import numpy as np
arr = np.array([1, 2, 3])
arr.astype('integer')

AThe array cannot be converted to integer type

BThe array must be converted using <code>astype(int)</code> without quotes

CThe string 'integer' is not a valid NumPy dtype name

DThe <code>astype()</code> method requires an additional argument

Step-by-Step Solution

Solution:

Step 1: Check dtype string validity
NumPy expects dtype names like 'int', 'int32', or 'int64', but 'integer' is not recognized.
Step 2: Confirm correct dtype usage
Using 'int' or int without quotes is valid, so 'integer' causes an error.
Final Answer:
The string 'integer' is not a valid NumPy dtype name -> Option C
Quick Check:
Use valid dtype names in astype() [OK]

Quick Trick: Use valid dtype names like 'int', not 'integer' [OK]
