CSII: Spring Final Exam

Python is an example of:

• a machine language

• a high-level programming language

• a natural language

The most important difference between integer and floating-point numbers lies in the fact that:

• integers cannot be literals, while floats can

• they are stored differently in the computer memory

• they cannot be used simultaneously

the // operator:

• performs integer division

• performs regular division

• does not exist

the result of the following addition:

123 + 0.0

• cannot be evaluated

• is equal to 123

• is equal to 123.0

Only one of the following statements is true - which one?

• addition precedes multiplication

• neither statement can be evaluated

• multiplication precedes addition

A value returned by the input() function is:

• a string

• a float

• an integer

An operator able to check whether two values are not equal is coded as:

• <>

• !=

• not ==

What value will be assigned to the x variable?:

z = 10

y = 0

x = z > y or z == y

• True

• False

• 1

The assignment:

vals = [0, 1, 2]

vals[0], vals[1] = vals[1], vals[2]

• shortens the list

• doesn't change the list's length

• extends the list

How many elements does the my_list contain?

my_list = [0 for i in range(1, 3)]

• one

• two

• three
