What is the output of the following code ?

निम्नलिखित कोड का परिणाम क्या है ?

import numpy as np
a = np.array([[1,2,3],[4,5,6],[7,8,9]])
print(a.shape)

(2, 3)

(3, 3)

(1,1)

None of these

Explanation:

The correct answer is:

(B) (3, 3)

The array a is a 2D NumPy array with 3 rows and 3 columns:
```
[[1, 2, 3],
 [4, 5, 6],
 [7, 8, 9]]
```
The .shape attribute of a NumPy array returns a tuple that gives the dimensions of the array (rows, columns).
In this case, the shape of the array is (3, 3), meaning 3 rows and 3 columns.

(B) (3, 3)
