Answer:
Following are the code to this question:
import ast as a #import package ast
d1= {}#defining an empty dictionary
def invert_dictionary(d1):#defining a method invert_dictionary
i = dict()#defining variable i that hold dict method
for k in d1:#defining for loo to check dictionary value
val = d1[k]#defining val variable to holds dictionary key values
for val1 in val:#defining another for loop to hold value of dictionary and inverse it
if val1 not in i:#defining if block to check value
i[val1] = [k]#hold key value
else:#defining else block
i[val1].append(k)#add value in dictionary
return i#return inverse value
with open("dict_items.txt", "r") as data:#use open method to add a list as a file
dict_item = a.literal_eval(data.read())#defining a variable that covert item as a text string in the input file
'''covert input string into dictionary item'''
e_val = input("Please enter a value")#defining variable e_val to input value
dict_item['4']=str(e_val)#holding value in dictionary
dict_item['5']='e'#holding value in dictionary
dict_item['6']='f'#holding value in dictionary
'''Invert the dictionary value '''
invert_data =invert_dictionary(dict_item)#defining variable to holding method value
'''calculating the format of each item of inverted dictionary as a text string output file.'''
f_data = {i:str(j[0]) for i,j in inverted_data.items() }#defining f_data to hold coverted value
import json as j#import package
with open('out_put.txt', 'w') as file:#use open method to open file
file.write(j.dumps(f_data))#add value
Explanation:
In the above-given code has four parts which can be defined as follows:
In the first part, a method invert_dictionary is defined that accepts a dictionary, and defines two for loops in which the second loop uses a conditional statement to convert the inverse form and return its value, and after inverse it use the open method to add a list as a file, and defining a variable that covert item as a text string in the input file.
In the second step, a variable e_val is declared for input value, and use the dict_item variable to holding dictionary value, and call the method and hold its value.
In the third and fourth step it calculating the format of each item of inverted dictionary as a text string output file.

Explanation:
A class is the blueprint for objects having similar attributes.
As much as classifying something means to define it based on the characteristics that is has that are similar to other things in that class, so also is a class here.
A class is the blueprint or rather template for making objects that have similar attributes which means that the class therefore gives the object its various attributes and its behavior.

When ordering a quadruple-shot latte, which contains four shots of espresso, you can also use the word quadruple to signify “four times as many.” The suffix quadric-, which means “four,” is the source of the Latin root quadruple, which means “create fourfold.”

Which example can be used to perform a binary search?
Answers
Answer:
In any case, binary search can be used to solve more extensive scope of problem, for example, finding the next smallest or next-biggest element in an array comparative with the target regardless of whether it is present or missing in the array.
Explanation:
In computer science, binary search, otherwise called logarithmic search, is a search calculation that finds the position of an objective incentive inside an arranged array. Binary search compares the target value to the center component of the array. In the event that they are not equivalent, the half in which the value can't lie is dispensed with and the search proceeds on the other half, again taking the center value to contrast with the target value, and continues this until the target value is found. On the off chance that the search ends with the other half being empty, the target value isn't in the array.
Binary search is quicker than linear search aside from small arrays. Nonetheless, the array should be arranged first to have the option to apply binary search. There are particular data structures intended for quick looking, for example, hash tables, that can be looked through more effectively than binary search.

we need to send 254 kbps over a noiseless channel with a bandwidth of 15 khz. how many signal levels do we need
Answers
Answer:
The level of the signal is 353.85
Explanation:
Data rate determines the speed of the data transmission.
The data rate depends on the following factors
The available bandwidthnumbers of signal levelsthe quality of the channel ( Means the level of noise )
The data is transmitted either from a noiseless channel or a noisy channel.
The given quality of the channel in the question is noiseless.
Use the following formula to calculate the signal levels
Bit rate = 2 x bandwidth x [tex]Log_{2}[/tex] ( signal level )
where
Transmitted Data = 254 kbps = 254,000 bps
Bandwidth = 15 khz = 15,000 hz
Placing values in the formula
254,000 = 2 x 15,000 x [tex]Log_{2}[/tex] ( L )
254,000 = 30,000 x [tex]Log_{2}[/tex] ( L )
254,000 / 30,000 = [tex]Log_{2}[/tex] ( L )
8.467 = [tex]Log_{2}[/tex] ( L )
L = [tex]2^{8.467}[/tex]
L = 353.85 levels
Recently, Walmart offered a wireless data contract based on bandwidth used, with a minimum monthly charge of $42 for up to 5 gigabytes (GB) of use.

What is the cost for a user who is expecting to use 9 GB
Answers
Answer:
For 9GB of data the user would pay $82 monthly!
Explanation:
To start off, our end goal is 9GB. We have the equation 9 = ? We can add up to our solutions with 1GB, 3GB, and 10GB. We can immediately rule out 10GB, since 9GB ≠ 10GB. To cost the least amount of money we can add up 3GB and 1GB = 4GB + 5GB = 9GB!
So, our equation is 3GB + 1GB + 5GB = 9GB, now lets figure out the cost!
$28 + $12 + $42 = $82
For 9GB of data the user would pay $82 monthly!

Write a program that asks the user how many names they have. (If they have a first name, two middle names, and a last name, for example, they would type 4.) Then, using a for loop, ask the user for each of their names. Finally, print their full name.
Answers
Answer:
The solution is implemented in python:
numnames = int(input("Number of Names: "))
nametitle = ["Surname: ","Firstname: ","Middlename: ","Middlename 2: "]
names = []
for i in range(numnames):
name = input(nametitle[i])
names.append(name)
print("Your fullname is: ",end=" ")
for i in names:
print(i,end=" ")
Explanation:
This prompts user for number of names
numnames = int(input("Number of Names: "))
This lists the name titles in a list
nametitle = ["Surname: ","Firstname: ","Middlename: ","Middlename 2: "]
This initializes an empty list
names = []
The following for loop get names from the user
for i in range(numnames):
name = input(nametitle[i])
names.append(name)
The following instructions print the user fullnames
print("Your fullname is: ",end=" ")
for i in names:
print(i,end=" ")
An example program in Python that asks the user for the number of names they have and then prompts them to enter each name.
It will then print their full name based on the names provided:
python
Copy code
num_names = int(input("How many names do you have? "))
names = []
for i in range(num_names):
name = input("Enter name {}: ".format(i + 1))
names.append(name)
full_name = " ".join(names)
print("Your full name is:", full_name)
In this program, we first ask the user to enter the number of names they have. The input is converted to an integer using int() since input() returns a string.
Then, we initialize an empty list names to store the names provided by the user.
Next, we use a for loop that iterates num_names times to ask the user for each name. The loop variable i starts from 0, so we add 1 to it when displaying the prompt using i + 1.
Inside the loop, we prompt the user to enter the name and append it to the names list. After the loop completes, we join all the names in the names list using the join() method with a space as the separator. This creates a single string representing the full name.
