NumPy - Creating Arrays

Which of the following is the correct syntax to create an uninitialized 3x2 array using np.empty()?

Anp.empty[3, 2]

Bnp.empty((3, 2))

Cnp.empty{3, 2}

Dnp.empty(3, 2)

Step-by-Step Solution

Solution:

Step 1: Recall correct shape argument format
NumPy expects shape as a tuple, so (3, 2) is correct.
Step 2: Check syntax correctness
Subscript notation invalid; curly braces invalid; separate arguments invalid.
Final Answer:
np.empty((3, 2)) -> Option B
Quick Check:
Shape argument must be a tuple (3, 2) [OK]

Quick Trick: Use tuple for shape: np.empty((rows, cols)) [OK]
