Improve error handling and add missing docstrings #92
Description
Multiple Code Quality Improvements
Hi! I'm contributing to Spamlyser as part of GirlScript Summer of Code (GSSoC) 2025. I've found several code quality improvements that can be addressed together:
1. Add Error Handling in Word Analyzer
File: models/word_analyzer.py (Line 697)
Problem: Potential KeyError in get_explanation_summary function
Fix: Use .get() method for safe dictionary access (e.g., w.get('position', 0))
2. Add Missing Docstrings
File: models/smart_preprocess.py
Problem: Functions like expand_abbreviations and correct_leetspeak lack docstrings
Fix: Add proper docstrings explaining parameters, return values, and functionality
3. Refactor Duplicated Code Logic
File: models/ensemble_classifier_method.py (Line 355)
Problem: get_all_predictions method duplicates existing logic
Fix: Use existing get_ensemble_prediction method in a loop instead
4. Add Meaningful Tests
File: tests/test_basic.py
Problem: Only contains placeholder test
Fix: Add tests for core functions like preprocess_message from smart_preprocess.py
Why These Matter
- Makes code more robust and crash-resistant
- Improves code readability for new contributors
- Reduces code duplication and maintenance burden
- Better test coverage prevents regressions
- Follows Python best practices

These improvements teach important software development practices: error handling, documentation, code reuse, and testing.
