2.Consider the following statements.
*1 Class attributes are more suitable for sharing data across instances of a class as opposed to instance variables.
*2 Instance variables always point to a common location in memory regardless of which instance of a class is used to access them

*4 In order to enable access to instance variables, functions must have a “self” argument.
*5 Composition represents an “is-a” relationship between two entities.

Which combination of statements is true?

5. The code class X(object): def __init__(self, J) can be interpreted as:
*Make a subclass X of class object that defines a constructor method that takes self and J as parameters

*Make a class X that inherits from an object class and has defined a constructor method that accepts as arguments the values of self and J
*All of the above

We will not do your homework for you, but will be glad to answer questions

actually you don't even need to write a code - that is a test and you need to study the learning material that you have and answer the questions.

You didn't provide any info on what you need help on, so let's start at the top:
