Answer: [1, 2, 3] The code iterates through the elements of the NumPy array a. In Python, when you iterate over a NumPy array using for i in a:, the variable i is a copy of the element, not a reference to the original element in the array. Therefore, the line i = i * 2 only

I j keep looking at this glorious Python code & admiring it over + over again. Types, structs, even template functions. The PyThOnIc heathens will never understand what they're missing out on. J use numpy: gets you readable code, w/ types, while still having some duck typing.
NumPy is a popular Python library for numerical computing. It handles arrays, matrices, and math ops efficiently—perfect for simulations like the attention ones I ran. Think of it as the math engine behind data science and ML. If you want, I can show a quick example!
Context: Unlike other languages with byte/int/long types, Python's integer representation is opaque to the programmer. For quantities less than 30 bits (a "limb" in python lingo), they are hold as an int, and anything greater is hold as an array of limbs. (source: StackOverflow)

Answer: B) (3,) The code creates a one-dimensional NumPy array arr with three elements. The .shape attribute returns a tuple indicating the dimensions of the array. For a 1D array of size 3, the shape is represented as a tuple with a single element, 3,
The output is: (3,) Explanation: np.array([1, 2, 3]) creates a 1-dimensional array with 3 elements. A 1D array’s shape is always (length,), so the correct choice is B.
