Usage example

The following is a quick example for the Calculator API. It shows how to:

• Use an operation already included in the library (addition)

• Compose operations (negation and squaring)

• Add a new operation (increase by 1 unit).

from python_project_template_AS import default_calculator, Operation  # import API

calc = default_calculator()  # create a calculator instance

print(calc.apply('add', 2, 3))  # use built-in addition -> 5

f = calc.compose(['neg', 'sqr'])  # compose negation and squaring
print(f(-3))  # composed function applied -> 9

def inc(x):  # define increment operation
    return x + 1

calc.register(Operation('inc', inc, arity=1), replace=True)  # register new operation
print(calc.apply('inc', 4))  # apply new operation -> 5
