A file named numbers.txt contains an unknown number of lines, each consisting of a single integer. Write some code that computes the sum of all these integers, and stores this sum in a variable name sum. *PYTHON*
Answers
f = open("numbers.txt", "r")
lst = [int(x) for x in f.read().splitlines()]
sum = 0
for x in lst:
----sum += x
I had to add the four dashes to maintain the structure of my code. You can replace them with spaces. Also, I wouldnt recommend having a variable named sum because python has a built in function named sum. You can test this code by putting print(sum) at the end of the code.

Which of the following is the strongest password?

O B. Thisismypassword
O C. 12345654321
O D. 8)oscysbydel%2
Answers
Answer:
Probably D
Explanation:
In what I have learned, I was taught that a strong password needs all of the following: Lowercase letters, Uppercase letters, Numbers, and Symbols, but the only one that has almost all of these, is D, because it has 2 numbers, 10 lowercase letters, and 1 symbol, the rest are just too obvious, (except for A) -_-
But other than that, I hope this is right, but if it is not i am very very sorry! :(
The strongest password is ttwEwtcaoaSm. The correct option is A.
What is a password?A password is a secret string of characters or symbols that is used to prove identity or gain access to a resource or computer system.
Passwords are used to safeguard sensitive data such as personal information, financial information, and online accounts.
A strong password is a difficult-to-guess or crack combination of letters, numbers, and symbols.
To maintain security, it is recommended that you use unique and complex passwords for each account and change them on a regular basis.
The strongest password is ttwEwtcaoaSm, which combines upper and lowercase letters, numbers, and special characters and is not a common phrase or word.
Thus, the correct option is A.

E.

Answers
One advantage of using object-oriented programming makes debugging the code easier. The correct option is B.
What is object-oriented programming?Programming in the object-oriented (OOP) manner identifies classes of objects that are closely related to the methods (functions) with which they are associated. It also covers the concepts of attribute and method inheritance.
Objects can be used in a variety of ways. Due to its modularity, extensibility, and reusability, object-oriented programming improves software development productivity when compared to traditional procedure-based programming techniques.
Functional programming, at its most basic, employs immutable data to instruct the program exactly what to do.
Therefore, the correct option is B. makes debugging the code easier.

Write the definition of a void function that takes as input an integer and outputs two times the number if it is even; otherwise it outputs five times the number.
Answers
Answer:
Written in C++
void number(int n){
if(n%2 == 0)
cout<<2 * n;
else
cout<<5 * n;
}
Explanation:
The programming language is not stated.
However, I answered using C++
This line defines the function as void
void number(int n){
This line checks if the number is even
if(n%2 == 0)
If yes, it doubles the number and prints the output
cout<<2 * n;
If otherwise,
else
It multiplies the number by 5 and prints the output
cout<<5 * n;
}
To call the function from main, use:
number(n);
Note than n must be declared as integer

Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.
Ex:
If the input is:
2011
18000
2018
where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:
Car's information:
Model year: 2011
Purchase price: 18000
Current value: 5770
Note: print_info() should use three spaces for indentation.
This is what is given
class Car:
def __init__(self):
self.model_year = 0
# TODO: Declare purchase_price attribute
self.current_value = 0
def calc_current_value(self, current_year):
depreciation_rate = 0.15
# Car depreciation formula
car_age = current_year - self.model_year
self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age)
# TODO: Define print_info() method to output model_year, purchase_price, and current_value
if __name__ == "__main__":
year = int(input())
price = int(input())
current_year = int(input())
my_car = Car()
my_car.model_year = year
my_car.purchase_price = price
my_car.calc_current_value(current_year)
my_car.print_info()
Answers
Answer:
Just add this and yoyr code should work.
Explanation:
def print_info(self):
print("Car's information:")
print(" Model year:", self.model_year)
print(" Purchase price:", self.purchase_price)
print(" Current value:", self.current_value)
Classes are templates used when an object is to be created while methods are functions that are executed when called or evoked
To declare the attribute purchase_price (type int), we make use of the self keyword, and we initialize the value to 0
So, the declaration of the purchase_price attribute is:
self.purchase_price = 0
To define the print_info() method, we simply evoke the model_year and the purchase_price attributes.
So, the definition of the print_info() method is:
def print_info(self):
print("Car's information:")
print(" Model year:", self.model_year)
print("Purchase price:", self.purchase_price)

The function that will be required to have the code with the output 4.6 and the aList will be [10, 23, 'bye'] is pop.
Code explanation:The code is written in python.
alist = [10, 23, 'bye', 4.6]
According to the python code, we used the variable "aList" to store a list. The list has a length of 4. It contains integers, float and string.
Using the pop function, the last value of the list will be removed.
The pop function removes the last value in a list.
alist.pop() removes 4.6 and it is printed out .
Then when we ask for our list, the list is printed out without the last value(4.6).
