NumPy - Creating Arrays

How can you create a 3D array of shape (2, 3, 4) with random floats and then flatten it into 1D?

Aarr = np.random.rand([2, 3, 4]) flat = arr.flatten()

Barr = np.random.rand(2, 3, 4) flat = arr.reshape(2, 3, 4)

Carr = np.random.rand(2, 3, 4) flat = arr.flatten()

Darr = np.random.rand(2, 3, 4) flat = arr.reshape(1, 24)

Step-by-Step Solution

Solution:

Step 1: Create 3D array with correct syntax
np.random.rand(2, 3, 4) creates 3D array of shape (2, 3, 4).
Step 2: Flatten array to 1D
Using arr.flatten() converts array to 1D with all elements.
Final Answer:
arr = np.random.rand(2, 3, 4) flat = arr.flatten() -> Option C
Quick Check:
flatten() makes 1D array [OK]

Quick Trick: Use flatten() to convert any array to 1D [OK]
