🛠️ Refactor suggestion
Add input validation and improve documentation.
The implementation is correct and Pythonic, but consider adding input validation to handle edge cases likeNone values or non-string types.

In simple_utils.py around lines 3 to 5, the reverse_string function lacks inputvalidation and detailed documentation. Add a type check at the start of thefunction 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 aTypeError will be raised for invalid inputs.| def count_words(sentence): | ||

🛠️ 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.

@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: defreverse_string(text):"""Reverses the characters in a string."""returntext[::-1]defcount_words(sentence):returnlen(sentence.split())defcelsius_to_fahrenheit(celsius):return (celsius*9/5)+32 For 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! |
