Python Coding Challange - Question with Answer (01300825)

 

This is testing NumPy arrays, reshaping, and transpose. Let’s go step by step.

---

Code:

import numpy as np
a = np.arange(6).reshape(2,3)
print(a.T.shape)

---

Step 1: np.arange(6)

• Generates numbers from 0 to 5.

np.arange(6) → [0 1 2 3 4 5]

---

Step 2: .reshape(2,3)

• Reshapes into a 2 rows × 3 columns array.

a =
[[0 1 2] 
 [3 4 5]]

So shape = (2, 3).

---

Step 3: a.T (transpose)

• Transpose swaps rows and columns.

a.T =
[[0 3]
 [1 4] 
 [2 5]]

Now it has 3 rows × 2 columns.

---

Step 4: .shape

• The new shape is (3, 2).

---

✅ Final Output:

(3, 2)
