What is the first class object in Python?

Is the first class created in Java?

Are functions first class in Java?
Functions as First Class Objects In the functional programming paradigm, functions are first class objects in the language. Functions can also be passed as parameters to other functions. In Java, methods are not first class objects.
What is a first-class value?
In computer programming, a first-class object, first-class citizen, or first-class value is a language entity (e.g., function or variable) that operates as other entities in a language. For example, in the C programming language, you cannot pass a function to another function as a parameter.
Is Python a typed language?
Python is both a strongly typed and a dynamically typed language. Strong typing means that variables do have a type and that the type matters when performing operations on a variable. For example Python allows one to add an integer and a floating point number, but adding an integer to a string produces error.
What is meant by ‘first class object’?

What exactly is a first class function?
First-class functions are a necessity for the functional programming style, in which the use of higher-order functions is a standard practice. A simple example of a higher-ordered function is the map function, which takes, as its arguments, a function and a list, and returns the list formed by applying the function to each member of the list.
Are functions first class objects in Python?
