NumPy - Array Data Types
Identify the error in this code snippet:
import numpy as np
arr = np.array([1000, 2000], dtype='int8')
print(arr)
ANo error, prints [1000 2000]
BSyntaxError due to dtype
CValueError: integer out of range
DValues overflow and wrap around silently
Step-by-Step Solution
Solution:
  1. Step 1: Check dtype and values

    The array uses int8 which can only hold -128 to 127, but values 1000 and 2000 are much larger.
  2. Step 2: Understand numpy overflow behavior

    Instead of error, numpy silently wraps values using modulo 256, causing overflow.
  3. Final Answer:

    Values overflow and wrap around silently -> Option D
  4. Quick Check:

    int8 overflow wraps large values silently [OK]
Quick Trick: Large values in small int types wrap silently, no error [OK]
Common Mistakes:
  • Expecting ValueError on overflow
  • Thinking values print as is
  • Confusing syntax error with dtype
