Answer:

Option I.

Explanation:

(I) Option (I). is true. If a class accepts different argument type and the argument type provided is different then it will throw a error. The argument type provided and the argument expecting has to match for the compilation of the program without an error. So, option (I) is true.

(II) Option (II). is false. If the method doesn't return any value then the method declaration contains $void$ as the return type.

(III) Option (III) is false. The method random() returns a double value with the number between 0.0 and 1.0 with 0.0 included in the range but 1.0 is not included in the range. The method returns value with positive side but not the negative side.

Write a Python program called wdcount.py which uses a dictionary to count the number of occurrences of each word (ignoring case)

Art [367]

The program is an illustration of loops.

<h3>What are loops?</h3>

Loops are program statements used to perform repetition

<h3>The wordcount.py program</h3>

The program written in Python, where comments are used to explain each line is as follows

# This opens the file in read mode

text = open("myFile.txt", "r")

# This creates an empty dictionary

d = dict()

#This iterates through the text

for line in text:

# This splits the line into words, after removing leading & trailing spaces, and newline characters

words = line.strip().lower().split(" ")

# This iterates through all the words

for word in words:

# The following if condition counts the occurrence of each word

if word in d:

d[word] = d[word] + 1

else:

d[word] = 1

#This prints the words and their frequencies, in descending order

for w in sorted(d, key=d.get, reverse=True):

print(w, d[w])

The birthday problem is as follows: given a group of n people in a room, what is the probability that two or more of them have t

Julli [10]

Answer:

import random

def calc_birthday_probability(num_people):

num_tries = 1e6

num_duplicates = 0

tries = 0

while tries < num_tries:

total_birthday = {}

for i in range(1, 366):

total_birthday[i] = 0

for count in range(num_people):

birthday = random.randint(1, 365)

if total_birthday[birthday] != 0:

num_duplicates += 1

break

total_birthday[birthday] += 1

tries += 1

return num_duplicates/num_tries

def main():

num_people = 10

p = calc_birthday_probability (num_people)

print(p)

num_people = 20

p = calc_birthday_probability (num_people)

print(p)

return

if __name__ == "__main__":

random.seed(2020)

main()

Explanation:

Run the loop until the value of tries is less than num_tries to do number of trials.
Run the loop to create the desired number of birthdays by generating random numbers.
Increase the num_duplicates variable by 1, if the birthday has already occurred.
Lastly define and then call the main function.

xz_007 [3.2K]

Answer:

access control list (ACL)

Explanation:

An access control list (ACL) is a list of authorization rights attached to an object - in other words, who can access that device or application and what can they do with it.

An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.

Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

Hence, an access control list primarily is composed of a set of permissions and operations associated with a file.
