open () is a function which returns an int that represents a physical file handle

the second open () argument is optional

instd, outstd, errstd are the names of pre-opened streams

if invoking open () fails, the value None is returned

the interpreter used to generate the file is version 3.6

it has been produced by CPython

it is the 36th version of the file

the file comes from the services . py source file

It outputs False

It outputs nothing

It outputs True

len(ClassB.__bases__) == 1

there can be more than one constructor in a Python class

the constructor must return a value other than None

the constructor is a method named __init__

a code point is a point inside the code when execution stops immediately

an escape sequence can be recognized by the # sign put in front of it.

UTF-8 is one of the ways of representing UNICODE code points.

ASCII is the name of a character coding standard

can return a value

cannot be invoked directly from inside the class

can be invoked directly from any of the subclasses

can be invoked directly from any of the superclasses

a is b

b( ) > 2

a() > 2

a is not None

121 + 1 != '!' + 2 * '2'

'AbC' lower () < 'AB'

'1' + '1' + '1' < '1' * 3'

'3.14' != str(3.1415)

the code is erroneus and it will not execute

it outputs [2, 4]

it outputs [4, 2]

it outputs [0, 1, 2, 3, 4]

the code will raise an unhandled exception

rearrange the source code to make it clearer

check the source code in order to see if its correct

execute the source code

translate the source code into machine code

the sys.path variable is a list of strings

_pycache_is a folder that stores semi-completed Python modules

a package contents can be stored and distributed as an mp3 file

a code designed to initialize a package's state should be placed inside a file named init.py

encapsulation allows you to protect some data from uncontrolled access

the arrows on a class diagram are always directed from a superclass towards its subclass

inheritance is the relation between a superclass and a subclass

an object is a recipe for a class

len(random.sample([1,2,3],2)) > 2

v1 == v2

random.choice([1,2,3]) >=1

v1 >= 1

it outputs -1

the code is erroneous and it will not execute

it outputs 1

it outputs 0

the constructor's first parameter identifies an object currently being created

the constructor cannot use the default values of the parameters

the constructor can be invoked directly under strictly defined circumstances

super-class constructor is invoked implicitly during constructor execution

Python strings are actually lists

Python strings can be concatenated

Python strings can be sliced like lists

Python strings are mutable

closing an open file is performed by the closefile ( ) function

the second open ( ) argument describes the open mode and defaults to ‘w’

if open ( ) ‘s second argument is ‘r’ the file must exist or open will fail

if open ( )’s second argument is ‘w’ and the invocation succeeds, the previous file’s content is lost
