Usage and Testing

The following is a quick example for the Calculator API.

from python_project_template_AS import default_calculator, Operation

# Create a default calculator (pre-populated with common operations)
calc = default_calculator()

# Apply an addition operation
print(calc.apply('add', 2, 3))  # -> 5

# Compose unary operations into a Callable
f = calc.compose(['neg', 'sqr'])
print(f(-3))  # -> 9

# Register a custom operation
def inc(x):
    return x + 1

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