Getting Started

# Install the package
pip install african-nlp

# Quick sentiment analysis
from african_nlp import SentimentAnalyzer

analyzer = SentimentAnalyzer(language='swahili')
result = analyzer.predict("Nimefurahi sana na huduma hii!")
print(result)  # {'sentiment': 'positive', 'confidence': 0.92}
