Duck typing is a concept associated with dynamic typing in Python, where the focus is on the behavior of an object rather than its actual type. In this context, the idea is that if an object has all the necessary methods and properties that are required for a specific task, it can be treated as that type, regardless of its actual class or the type it was originally intended to represent. This approach follows the principle often summarized by the phrase, "If it looks like a duck and quacks like a duck, it must be a duck."
By evaluating an object based on what it can do—its methods and properties—rather than restricting it to a certain class or type, Python allows for more flexible and adaptable code. This means that as long as an object fits the required interface for a function, it can be passed to that function without concern for its underlying type, thus promoting polymorphism and reducing dependency on inheritance hierarchies.
In contrast, the other choices imply more rigid type checking practices that are contrary to the essence of duck typing. For instance, determining an object's type strictly by its class or enforcing type hints would limit the flexibility that duck typing affords, and enforcing strict type checking could undermine the benefits of dynamic typing that Python offers.
