What is a key advantage of Python's 'duck typing'?
What is a key advantage of Python's 'duck typing'?
- It requires explicit type declarations for all variables, improving code clarity.
- It allows objects to be used based on their behavior rather than their declared type. (correct)
- It enforces strict type checking at compile time, preventing type-related errors.
- It automatically converts data types, ensuring seamless integration with other languages.
