in python

1.The only operator that cannot be overloaded is the subscript operator.

True

False

2.Which of the following is not true about unit testing

		The purpose of unit testing is to validate that each unit of the software performs as designed
		Unit testing increases confidence in changing/ maintaining code
		With unit testing development of software is slower.
		Unit testing leads to code that is easier to reuse

3.A class can define the behavior for the < operator

True

False

4.By default calling the str function on a custom object will

		print a description of that object
		print the name of the object
		print the name of the class
		print the memory address of that object

5.

The method name for non-integer division is

		__div__
		__truediv__
		/
		//

6.

What does operator overloading mean?

		The ability to alter how arithmetic operators work with integers.
		The ability to have operators work with instances of programmer defined classes=.
		The ability to alter the rules of precedence.
		The ability to alter create new operators.

7.

In white-box testing we do not need to know anything about the internal structure, design, or implementation of the software being tested.

True

False

8.

By default, if you use the + operator on two user-defined objects

		a new object will be created
		the two object will be added
		the two objects will be combined
		an error will occur

9.

Assuming that the __add__ operator is implemented for two objects, x and y, then x+y is equivalent to

		add(x,y)
		__add__(x,y)
		x.__add__(y)
		y.__add__(x)

10.

Typically, a definition of the __add__ method should:

		Change the left operand
		Return an new instance of the right operand type
		Change the right operand
		Return an new instance of the left operand type
