# Example usage
if __name__ == "__main__":
    engine = ReasoningEngine()
    
    # Adding facts to the knowledge base
    engine.add_knowledge("A", True)
    engine.add_knowledge("B", False)

    print(engine)  # Should output: ReasoningEngine with knowledge base: {'A': True, 'B': False}

    # Making a deduction based on the added facts
    result = engine.deduce("A and B")
    print(result)  # Should output: False

    result = engine.deduce("not A or not B")
    print(result)  # Should output: True
```

This example demonstrates how to create a simple reasoning engine capable of handling basic logical operations based on facts stored in its knowledge base.
