What is a duck typing in Python?
Duck Typing is a type system used in dynamic languages. For example, Python, Perl, Ruby, PHP, Javascript, etc. where the type or the class of an object is less important than the method it defines. Using Duck Typing, we do not check types at all. Instead, we check for the presence of a given method or attribute.
What is dynamic typing and duck typing?

In duck typing, an object is of a given type if it has all methods and properties required by that type.
Why is duck typing good?
