3-5: Good implementation with room for robustness improvements.The string reversal logic using slicing is correct and efficient. However, consider adding input validation to handle edge cases like
Noneor non-string inputs.Consider this enhanced version with type hints and validation:
-def reverse_string(text): +def reverse_string(text: str) -> str: """Reverses the characters in a string.""" + if not isinstance(text, str): + raise TypeError("Input must be a string") return text[::-1]
1-12: Consider adding comprehensive type hints and consistent error handling.The utility functions are well-implemented, but the module would benefit from consistent documentation and error handling patterns throughout.
For a more professional utility library, consider:
- Type hints: Add type annotations to all functions for better IDE support and documentation
- Consistent docstrings: All functions should have docstrings following the same format
- Input validation: Implement consistent error handling strategies
- Module docstring: Add a module-level docstring describing the utilities
Example module header:
""" simple_utils.py - A collection of simple utility functions This module provides basic utility functions for string manipulation, text processing, and unit conversions. """

🛠️ Refactor suggestion
Add documentation and numeric validation for consistency.
The temperature conversion formula is mathematically correct, but the function lacks a docstring and input validation, making it inconsistent with the module's style.
Apply this diff to improve consistency and robustness:
-def celsius_to_fahrenheit(celsius):
+def celsius_to_fahrenheit(celsius: float) -> float:
+ """Converts temperature from Celsius to Fahrenheit."""
+ if not isinstance(celsius, (int, float)):
+ raise TypeError("Input must be a number")
return (celsius * 9/5) + 32📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In python/simple_utils.py around lines 10 to 11, the function
celsius_to_fahrenheit lacks a docstring and input validation. Add a clear
docstring explaining the function's purpose, input, and output. Also, include a
numeric type check for the input parameter and raise a TypeError if the input is
not a number to ensure consistency and robustness.

The word counting logic is correct, but the function lacks a docstring and input validation, making it inconsistent with reverse_string.

In python/simple_utils.py around lines 7 to 8, the count_words function lacks a
docstring and input validation, which reduces consistency and robustness. Add a
clear docstring explaining the function's purpose, parameters, and return value.
Also, include input validation to check if the input is a string and raise a
TypeError if not, matching the style used in the reverse_string function.
