🛠️ Refactor suggestion
Add input validation and improve documentation.
The implementation is correct and Pythonic, but consider adding input validation to handle edge cases like None values or non-string types.

In simple_utils.py around lines 3 to 5, the reverse_string function lacks input
validation and detailed documentation. Add a type check at the start of the
function to ensure the input is a string and raise a TypeError if not. Also,
update the docstring to specify the expected input type and mention that a
TypeError will be raised for invalid inputs.

Add documentation and input validation.
The function lacks documentation and input validation. Consider the following improvements:

In simple_utils.py around lines 7 to 8, the count_words function lacks a
docstring and input validation. Add a clear docstring explaining the function's
purpose, parameters, and return value. Also, include input validation to check
that the sentence argument is a string and raise a TypeError if not.

🛠️ Refactor suggestion
Add documentation, input validation, and type hints.
The conversion formula is mathematically correct, but the function needs documentation and input validation for robustness.

type hints for the input parameter and return type. Add input validation to
check that the input is a number (int or float) and raise a TypeError if not.

@coderabbitai Why do all of these functions need docstrings? Isn't it obvious enough what they do? |

Tip For best results, initiate chat on the files or code changes. 🧩 Analysis chainI need to examine the actual code to give you a thoughtful response about the docstring requirements. 🏁 Script executed: Length of output: 305 @HammerHam You make a fair point! Looking at your code, these function names are indeed very self-explanatory: def reverse_string(text):
"""Reverses the characters in a string."""
return text[::-1]
def count_words(sentence):
return len(sentence.split())
def celsius_to_fahrenheit(celsius):
return (celsius * 9/5) + 32For simple utility functions like these, you're right that the function names clearly communicate their purpose. The implementations are straightforward single-line operations that don't really need explanation. However, there's a slight inconsistency -
The most important thing is consistency within your codebase. If this is a personal project or internal utility where the function names are clear (which they are), minimal or no docstrings is perfectly reasonable. Docstrings become more valuable for complex functions, public APIs, or when you need to document edge cases, parameter types, or non-obvious behavior. Your approach of self-documenting code through clear naming is actually a good practice! |
