Answer:
Race race = new Race(track, car);
Explanation:
Complete code fragment is as follows:
Track track = new Track();
Car car = mycar;
Race race = new Race(track,car);
Here we are declaring a variable race of the type Race which is initialized to new instance of Race class. The constructor of race takes up the following 2 arguments:
1) New Instance of Track class;
2) Previously defined reference to an object of type Car.
Answer:
Take a String.
Convert it into array of characters.
Apply for loop till length of char array.
Using isDigit() method we can check the digits in string.
If isDigit() will return true then print that index value.
That digit is in char form. ...
Using sum variable, we will sum it.

Answer:
c. Dark Web
Explanation:
Surface web is also called visible web is a part of world wide web that can be easily searchable using search engines as its contents are indexed by the search engines such as Google and its contents are accessible by public using standard web browsers. So a is not a suitable choice.
Deep Web is called invisible web as it is not accessible or searchable to standard search engines like Google. Search engines cannot index the contents of these sites. However such sites do not requires specialized browsers to access. So b is not a suitable choice.
Dark Web: It is a part of Deep Web sites but it requires specialized software and browsers to access. These sites cannot be indexed and cannot be searchable through standard search engines. This is also called dark side of the world wide web darker which is frequently used by criminals, hackers, black markets, hit-men. Illegal activities on a massive level is takes place in the dark web such as access to stolen sensitive information, malware, drug trade and terrorist operations. These sites are temporary and keep changing addresses to lessen the risk of getting caught by govt agencies or security officials. So c is the suitable choice.
Crypto-Net is a kind of neural network which works with encrypted data which can make a prediction based on the data without disclosing the data and prediction to the 3rd party. So d is not a suitable option.
Answer:
Add this statement at the end of your steps() function
return ""
This statement will not print None at the end of steps.
Explanation:
Here is the complete function with return statement added at the end:
def steps(number): # function steps that takes number (number of steps to print) as parameter and prints the steps specified by number
i = 1 #assigns 1 to i
while i < number + 1:
string = str(i) * 3 #multiplies value of i by 3 after converting i to string
string1 = str(string) # stores the step pattern to string1
if i != 0: # if the value of i is not equal to 0
string1 = (i * 4*' ' + "\b" + "\b" + "\b" + "\b") + string #set the spaces between steps
elif i == 1: # if value of i is equal to 1
string1 = string #set the string to string1
print(string1) # print string1
i = i + 1 # increments i at each iteration
return "" #this will not print None at the end of the steps and just add a an empty line instead of None.

Answer:
import numpy as np
word = input("Enter a word: ")
acc = []
with open("Downloads/record-collection.txt", "r") as file:
lines = file.readlines()
for line in lines:
if word in line:
line = line.strip()
acc.append(int(line[0]))
if np.mean(acc) >= 2:
print(f"The word {word} is a positive word")
print(f"{word} appeared {len(acc)} times")
print(f"the review of the word {word} is {round(np.mean(acc), 2)}")
else:
print(f"the word {word} is a negative word with review\
{round(np.mean(acc), 2)}")
Explanation:
The python program gets the text from the review file, using the user input word to get the definition of reviews based on the word, whether positive or negative.
The program uses the 'with' keyword to open the file and created the acc variable to hold the reviews gotten. The mean of the acc is calculated with the numpy mean method and if the mean is equal to or greater than 2 it is a positive word, else negative.
