Calculator class with add, subtract, multiply, and divide methods - Support for both integers and floating-point numbers - Comprehensive error handling for division by zero - Functional interface via calculate() function for convenience - Type hints (Union[int, float]) for better IDE support - Detailed docstrings with usage examples for all methods Implementation Details: - Created src/ directory structure - Added __init__.py to make src a proper Python package - Included demo code in __main__ block - Added .gitignore for Python projects Quality Attributes: - Clean, maintainable code structure - Proper error handling with meaningful messages - Type safety with full type annotations - Comprehensive documentation - Production-ready with edge case handling All operations tested and verified working correctly. --- .gitignore | 37 ++++++++++ src/__init__.py | 10 +++ src/calculator.py | 174 ++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 221 insertions(+) create mode 100644 .gitignore create mode 100644 src/__init__.py create mode 100644 src/calculator.py diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..c6f9226 --- /dev/null +++ b/.gitignore @@ -0,0 +1,37 @@ +# Python +__pycache__/ +*.py[cod] +*$py.class +*.so +.Python +build/ +develop-eggs/ +dist/ +downloads/ +eggs/ +.eggs/ +lib/ +lib64/ +parts/ +sdist/ +var/ +wheels/ +*.egg-info/ +.installed.cfg +*.egg + +# Virtual environments +venv/ +ENV/ +env/ + +# IDE +.vscode/ +.idea/ +*.swp +*.swo +*~ + +# OS +.DS_Store +Thumbs.db diff --git a/src/__init__.py b/src/__init__.py new file mode 100644 index 0000000..8e47716 --- /dev/null +++ b/src/__init__.py @@ -0,0 +1,10 @@ +""" +Source code package for the agentic-workflow-test repository. + +This package contains the calculator module and other implementations. +""" + +from .calculator import Calculator, calculate + +__all__ = ['Calculator', 'calculate'] +__version__ = '1.0.0' diff --git a/src/calculator.py b/src/calculator.py new file mode 100644 index 0000000..c2fdf89 --- /dev/null +++ b/src/calculator.py @@ -0,0 +1,174 @@ +""" +Calculator module providing basic arithmetic operations. + +This module implements a Calculator class with support for addition, subtraction, +multiplication, and division operations with proper error handling. +""" + +from typing import Union + +Number = Union[int, float] + + +class Calculator: + """ + A simple calculator class that supports basic arithmetic operations. + + This class provides methods for addition, subtraction, multiplication, + and division with proper error handling for edge cases like division by zero. + """ + + def add(self, a: Number, b: Number) -> Number: + """ + Add two numbers together. + + Args: + a: The first number + b: The second number + + Returns: + The sum of a and b + + Example: + >>> calc = Calculator() + >>> calc.add(5, 3) + 8 + """ + return a + b + + def subtract(self, a: Number, b: Number) -> Number: + """ + Subtract the second number from the first. + + Args: + a: The number to subtract from + b: The number to subtract + + Returns: + The difference of a and b + + Example: + >>> calc = Calculator() + >>> calc.subtract(10, 3) + 7 + """ + return a -

Each operation is a method that takes two numbers and returns the result. + +#### Creating a Calculator + +```python +from src.calculator import Calculator + +calc = Calculator() +``` + +The calculator has no state, so you can create one instance and reuse it throughout your application, or create new instances as needed. + +#### Addition + +Add two numbers together: + +```python +calc.add(5, 3) # 8 +calc.add(-10, 5) # -5 +calc.add(2.5, 3.7) # 6.2 +calc.add(5, 3.5) # 8.5 (mixed int/float) +``` + +#### Subtraction + +Subtract the second number from the first: + +```python +calc.subtract(10, 3) # 7 +calc.subtract(-5, -3) # -2 +calc.subtract(7.5, 2.5) # 5.0 +calc.subtract(10, 3.5) # 6.5 +``` + +#### Multiplication + +Multiply two numbers together: + +```python +calc.multiply(4, 5) # 20 +calc.multiply(-4, 5) # -20 +calc.multiply(2.5, 4) # 10.0 +calc.multiply(3, 2.5) # 7.5 +``` + +#### Division + +Divide the first number by the second: + +```python +calc.divide(10, 2) # 5.0 +calc.divide(7, 2) # 3.5 +calc.divide(-10, 2) # -5.0 +calc.divide(7.5, 2.5) # 3.0 +``` + +**Important**: Division always returns a float, even when dividing integers that result in a whole number. + +### The calculate() Function + +The `calculate()` function provides a functional interface that's useful when you want to perform a single operation or when the operation type is determined dynamically. + +#### Syntax + +```python +calculate(operation, a, b) +``` + +- **operation** (str): The operation to perform: `'add'`, `'subtract'`, `'multiply'`, or `'divide'` +- **a** (int or float): The first operand +- **b** (int or float): The second operand +- **returns**: The result of the operation + +#### Examples + +```python +from src.calculator import calculate + +# Basic usage +calculate('add', 10, 5) # 15 +calculate('subtract', 10, 5) # 5 +calculate('multiply', 10, 5) # 50 +calculate('divide', 10, 5) # 2.0 + +# Dynamic operation selection +operations = ['add', 'subtract', 'multiply', 'divide'] +for op in operations: + result = calculate(op, 10, 5) + print(f"{op}: {result}") + +# User input +operation = input("Enter operation: ") # User enters 'add' +num1 = float(input("First number: ")) # User enters 10 +num2 = float(input("Second number: ")) # User enters 5 +result = calculate(operation, num1, num2) +``` + +--- + +## Type System + +The calculator supports both integers and floats and handles them seamlessly. + +### Supported Types + +```python +# Integers +calc.add(5, 3) # ✓ Works + +# Floats +calc.add(5.5, 3.2) # ✓ Works + +# Mixed types +calc.add(5, 3.5) # ✓ Works +calc.multiply(3, 2.5) # ✓ Works +``` + +### Return Types + +- **Addition, Subtraction, Multiplication**: Returns the natural result type + - Integer + Integer = Integer + - Float + Float = Float + - Integer + Float = Float + +- **Division**: Always returns a float + ```python + calc.divide(10, 2) # Returns 5.0 (float) + calc.divide(7, 2) # Returns 3.5 (float) + ``` + +### Type Hints + +All functions include proper type hints for better IDE support: + +```python +from typing import Union + +Number = Union[int, float] + +def add(self, a: Number, b: Number) -> Number: + ... +``` + +--- + +## Error Handling + +The calculator provides robust error handling with clear, descriptive error messages. + +### Division by Zero + +Attempting to divide by zero raises a `ValueError`: + +```python +from src.calculator import Calculator + +calc = Calculator() + +try: + result = calc.divide(10, 0) +except ValueError as e: + print(f"Error: {e}") + # Output: Error: Cannot divide by zero +``` + +This applies to both the class method and the functional interface: + +```python +from src.calculator import calculate + +try: + result = calculate('divide', 10, 0) +except ValueError as e: + print(f"Error: {e}") + # Output: Error: Cannot divide by zero +``` + +### Invalid Operations + +The `calculate()` function raises a `ValueError` for invalid operation names: + +```python +from src.calculator import calculate + +try: + result = calculate('power', 2, 3) +except ValueError as e: + print(f"Error: {e}") + # Output: Error: Unknown operation: power.
