Modify in-place when possible: Follow Python's mutable object conventions Return self: Allows method chaining and matches built-in behavior Handle different types: Check operand types and raise TypeError if needed Consider immutability: Return new objects for immutable types Document behavior: Clearly ...
Matrix multiplication is associative, so chaining operations with @ works as expected. The operations are performed left-to-right, with each @ calling __matmul__ on its left operand. NumPy optimizes such chains internally when possible, reducing temporary allocations. The syntax remains clean ...
