NumPy - Creating Arrays

You want to create a NumPy array from a list of strings representing numbers, like ['1', '2', '3'], but want the array to have integer type. Which code achieves this?

Anp.array(['1', '2', '3'], dtype=object)

Bnp.array(['1', '2', '3']).astype(str)

Cnp.array(['1', '2', '3'], dtype=int)

Dnp.array(['1', '2', '3'], dtype=float)

Step-by-Step Solution

Solution:

Step 1: Convert string numbers to integers
Using dtype=int converts string elements to integers during array creation.
Step 2: Confirm correct dtype usage
np.array(['1', '2', '3'], dtype=int) correctly specifies dtype=int to get integer array.
Final Answer:
np.array(['1', '2', '3'], dtype=int) -> Option C
Quick Check:
dtype=int converts string numbers to integers [OK]

Quick Trick: Use dtype=int to convert string numbers to integers [OK]

Common Mistakes:

Using astype(str) instead of int
Using dtype=object keeps strings
Using dtype=float when integers needed
