Code Review:
I'll review the code and provide feedback on different aspects:
**Positive Aspects:**
1. Well-structured and organized code with clear class and method definitions
2. Comprehensive docstrings following good documentation practices
3. Type hints are used consistently throughout the code
4. Good error handling for division by zero
5. Clear separation of concerns with distinct methods for different operations
6. Includes example usage and test cases
7. Good use of memory functionality for calculator operations
8. Clean implementation of basic arithmetic operations
**Suggestions for Improvement:**
1. **Input Validation:**
'''python
def add(self, x: float, y: float) -> float:
# Add input validation
if not isinstance(x, (int, float)) or not isinstance(y, (int, float)):
raise TypeError("Arguments must be numbers")
self.last_result = x + y
return self.last_result
'''
2. **Constants Definition:**
'''python
class Calculator:
DEFAULT_VALUE = 0 # Define constants at class level
def __init__(self):
self.memory = self.DEFAULT_VALUE
self.last_result = self.DEFAULT_VALUE
'''
3. **Property Decorators:**
'''python
@property
def last_result(self) -> float:
return self._last_result
@last_result.setter
def last_result(self, value: float) -> None:
self._last_result = value
'''
4. **Add Testing Framework:**
'''python
import unittest
class CalculatorTests(unittest.TestCase):
def setUp(self):
self.calc = Calculator()
def test_add(self):
self.assertEqual(self.calc.add(2, 3), 5)
'''
5. **Method Return Type Consistency:**
- Consider returning `self` from methods like `clear()`, `store_in_memory()`, and `clear_memory()` to enable method chaining
6. **Add Rounding Control:**
'''python
def __init__(self, precision: int = 10):
self.memory = 0
self.last_result = 0
self.precision = precision
def _round_result(self, value: float) -> float:
return round(value, self.precision)
'''
7. **Add More Advanced Features:**
- Consider adding support for operations with multiple numbers
- Add support for mathematical functions (square root, power, etc.)
8. **Error Messages:**
'''python
class CalculatorError(Exception):
"""Custom exception for calculator errors"""
pass
# Use custom exception
if y == 0:
raise CalculatorError("Division by zero is not allowed")
'''
9. **Add Context Manager Support:**
'''python
def __enter__(self):
return self
def __exit__(self, exc_type, exc_val, exc_tb):
self.clear()
'''
10. **Add Logging:**
'''python
import logging
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)
def add(self, x: float, y: float) -> float:
logger.debug(f"Adding {x} and {y}")
self.last_result = x + y
return self.last_result
'''
**Security Considerations:**
- Consider adding input sanitization if the calculator will be used with user input
- Add bounds checking for very large numbers to prevent overflow
- Consider adding protection against floating-point precision errors
**Performance Considerations:**
- The current implementation is efficient for basic calculations
- For heavy usage, consider caching frequently used results
- For complex calculations, consider using decimal.Decimal for better precision
The code is well-written overall, but implementing some of these suggestions would make it more robust and feature-complete. The choice of which improvements to implement would depend on the specific use case and requirements of the project.
