NumPy - Array Data Types
What does specifying dtype when creating a NumPy array do?
AIt sets the type of data stored in the array.
BIt changes the shape of the array.
CIt sorts the array elements.
DIt deletes elements from the array.
Step-by-Step Solution
Solution:

  1. Step 1: Understand the role of dtype in NumPy

    The dtype parameter defines the type of data (like int, float) stored in the array.

  2. Step 2: Compare with other options

    Changing shape, sorting, or deleting elements are unrelated to dtype.

  3. Final Answer:

    It sets the type of data stored in the array. -> Option A

  4. Quick Check:

    dtype controls data type = A [OK]
Quick Trick: dtype controls data type stored in array [OK]
Common Mistakes:
  • Confusing dtype with array shape
  • Thinking dtype sorts or deletes elements
  • Assuming dtype changes array size
