Since Python 3.5, it’s been possible to use@to multiply matrices. For example, let’s create a matrix class, and implement the__matmul__()method for matrix multiplication: classMatrix(list):def__matmul__(self,B):A=selfreturnMatrix([[sum(A[i][k] *B[k][j]forkinrange(len(B)))fo...
Python is a highly cost-effective solution when users add the free extensive standard library and Python interpreter into the mix. It is highly versatile. For example, users can quickly engage in edit-test-debugging cycles with no compilation step needed. For these and other reasons, software de...
