Python Coding challenge - Day 677| What is the output of the following Python Code?

 

Code Explanation:

1) Importing PyTorch

import torch

Loads the PyTorch library.

Gives access to tensors and mathematical operations like matrix multiplication.

2) Creating the First Tensor

a = torch.tensor([[1,2],[3,4]])

Defines a 2×2 tensor a.

Internally stored as a matrix:

a=[1 2

     3 4]

3) Creating the Second Tensor

b = torch.tensor([[5,6],[7,8]])

Defines another 2×2 tensor b.

b=[5 6

     7  8]

4) Matrix Multiplication

c = torch.matmul(a, b)

Performs matrix multiplication (not element-wise).

5) Converting to List & Printing

print(c.tolist())

.tolist() converts the tensor into a standard Python nested list.

Prints the matrix result in list format.

Final Output

[[19, 22], [43, 50]]
