python_project_template_AS.operations

Operation container and a few example math operations.

The Operation is a tiny callable wrapper that validates arity and delegates to the underlying function. A small set of convenience instances (ADD, SUB, MUL, DIV, NEG, SQR) are provided for tests/examples.

Functions

add(a, b)	Return the sum of two numbers.
mul(a, b)	Return the product of two numbers.
neg(a)	Return the numeric negation of a value.
safe_div(a, b)	Divide a by b, raising OperationError on zero division.
square(a)	Return the square of a value.
sub(a, b)	Return the difference of two numbers.

Classes
