Answer:
class Phone(object):
def __init__(self, features, phones=[]):
self.features = features
self.phones = phones
Explanation:
In python object-oriented programming, an instance variable of a class object is created in the "__init__()" method. the "self" is a convention name used to represent the instance of an object class. The input values are assigned to the object variable with the self.'argument_name' statement.
When the phone argument is not given, the self.phones variable is initialized as an empty list.
Answer:
Scope.
Explanation:
In programming, the scope could be static, private or public and in those, defines the scope of a specific variable.
Ex.
public int x = 0; // Can be seen when called within a whole class and outside of a class/ function.
private int y = 0; // Can be seen only within the class its defined in.
static pub/priv int z = 0; // Uncangeable variable that can be defined in both class and external class, depending on the two prior scopes defined after.
int aa = 0; // Defaults to private.
Answer:
ummm what system. have to be more specific ^^
Explanation:
Question:
Write a function that adds together all values from 0 to a given value and returns the final number. For example, if the given value is `4`, you would add 0 + 1 + 2 + 3 + 4
Answer:
In Python:
def add_to_value(n):
sum = 0
for i in range(n+1):
sum = sum + i
return sum
Explanation:
This line defines the function
def add_to_value(n):
This line initializes sum to 0
sum = 0
The following iteration adds from 0 to n
<em> for i in range(n+1):</em>
<em> sum = sum + i</em>
This line returns the calculated sum
return sum
