We know that Python is a dynamically typed language; there are no type declarations. The type of parameter x is not declared, we can send any type of object to this function. We could send a list object or a str
This type of polymorphism is often associated with upcasting, which happens when a parent class points to an instance of the child’s class. Polymorphism can also be implemented in other ways in OOP, including: Ad-hoc polymorphism. A function is applied to different arguments and might operate...
Pythondynamic languagespolymorphismtrace-based analysisFollowing the increased popularity of dynamic languages and their increased use in critical software, there have been many proposals to retrofit static type system to these languages to improve possibilities to catch bugs and improve performance.Akerblom...
To show how Python can use each of these different class types in the same way, we can first create aforloopthat iterates through atupleof objects. Then we can call the methods without being concerned about which class type each object is. We will only assume that these methods actually ...

resolved at compile-time based on the class type rather than at runtime based on the object type. Therefore, static methods cannot be overridden or exhibit polymorphic behavior. When you call a static method, it is always the version defined in the class in which it is declared that gets ...
