easy📝 Conceptual Q11 of 15

NumPy - Array Data Types

A<code>int64</code>

B<code>int16</code>

C<code>int8</code>

D<code>int32</code>

Step-by-Step Solution

Solution:

Step 1: Understand integer type sizes
Each numpy integer type uses a different number of bits: int8 uses 8 bits, int16 uses 16 bits, int32 uses 32 bits, and int64 uses 64 bits.
Step 2: Identify the smallest size
Since 8 bits is the smallest size, int8 uses the least memory.
Final Answer:
int8 -> Option C
Quick Check:
Smallest bits = int8 [OK]

Quick Trick: Smaller int types use fewer bits and less memory [OK]
