[Solved] Identify the error in this code:import numpy as np arr = np.ones(3, 3) print(arr) — Ans: Shape must be a single tuple, not two separate arguments | NumPy

NumPy - Creating Arrays

Identify the error in this code:

import numpy as np
arr = np.ones(3, 3)
print(arr)

AShape must be a single tuple, not two separate arguments

Bnp.ones() cannot create arrays of size 3

CMissing dtype argument causes error

Dnp.ones() requires a list, not integers

Step-by-Step Solution

Solution:

Step 1: Check the function call syntax
np.ones() expects the shape as a single argument, usually a tuple for multiple dimensions.
Step 2: Identify the error
Passing two separate integers 3, 3 is invalid; it should be np.ones((3, 3)).
Final Answer:
Shape must be a single tuple, not two separate arguments -> Option A
Quick Check:
Shape argument must be a tuple for multi-D arrays [OK]

Quick Trick: Pass shape as one tuple, not separate numbers [OK]
