Answer:
- To get the items of a dictionary and print them as a string, use the items() method to unpack the keys and values in a for and print or write them into a file.
for key, value in mydict.items():
print(f"{key}, {value}")
- To convert string from user input into dictionary;
mystring = input().split(" ") #assuming the words are separated by a space.
from word in mystring:
mydict[word] = mydict.get(word, 0) + 1
This would use the words in the string as the keys of the dictionary and the count of each word as the respective values.
Explanation:
A dictionary is a data structure in python used to store data in key-value pairs. The items are enclosed in curly braces and can be accessed with the key in dot or bracket notation.
Dictionaries in Python are used to represent data items in pairs; i.e. key and values
(a) Format items as strings in an input file
To do this we make use of the file manipulation.
Assume the dictionary name is given as: myDict

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.
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.

we need to send 254 kbps over a noiseless channel with a bandwidth of 15 khz. how many signal levels do we need
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
Modify your program from Learning Journal Unit 7 to read dictionary items from a file and write the inverted dictionary to a file. You will need to decide on the following: How to format each dictionary item as a text string in the input file. How to covert each input string into a dictionary item. How to format each item of your inverted dictionary as a text string in the output file. Create an input file with your original three-or-more items and add at least three new items, for a total of at least six items.
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.
The distance a vehicle travels can be calculated as follows: distance = speed * time For example: If a train travels 40 miles per hour for 3 hours, the distance traveled is 120 miles.Write a program that asks the user for the speed of a vehicle (in miles per hour) and how many hours it has traveled. The program should use a loop to display the distance the vehicle has traveled for each hour of the time period.
Answer:
In Python:
speed = float(input("Speed: (mile/hr): "))
time = int(input("Time: (hr): "))
for hour in range(1,time+1):
distance = speed * hour
print("Distance: "+str(speed)+"*"+str(hour)+" = "+str(distance))
Explanation:
This prompts the user for speed in mile/hr
speed = float(input("Speed: (mile/hr): "))
This prompts the user for time in hr
time = int(input("Time: (hr): "))
This iterates through the input time
for hour in range(1,time+1):
This calculates the distance covered in each hour
distance = speed * hour
This prints the distance covered in each hour
print("Distance: "+str(speed)+"*"+str(hour)+" = "+str(distance))

private static int positionMin (int] vals, int startPosition) {
int minPosition startPosition;
for (int i startPosition; i
if (vals[i] vals[min Position]) {
minPosition = i;
return min
Position; private static void swap(int] vals, int firstPosition, int secondPosition) {
int temp; temp vals[firstPosition];
vals[firstPosition] vals[second Position];
vals[secondPosition] temp return public static void selSort(int| vals) {
int minPos for (int startPos 0; startPos< vals.length; startPos++){
minPos positionMin(vals,startPos); swap(vals,startPos, min Pos) ;
for (int i 0; i< vals.length; i++) { if(i
}else Jelse { System.out.println(vals[i]); } }; }
return; } }
Answer:
Explanation:
Since there are no line numbers in this question I will start counting from public class SelectionSort{ as line 1 and so on, as well as provide the code on that line.
The index of the smallest value is returned on line 8 where it says return min which shouldn't have any spaces and should be return minPosition;
The input array is given as an argument at the beginning of the function on line 2 where it says private static int positionMin (int] vals, int startPosition) {, as the variable vals.
This input array is also used as an argument on line 10 where it says Position; private static void swap(int] vals, int firstPosition, int secondPosition) and line 15 where it says vals[secondPosition] temp return public static void selSort(int| vals) {

Authorized agent Confidentiality Integrity Encryption 6:53 PM ______ means that only people with the right permission can access and use information.
Answer:
The answer is "Confidentiality"
Explanation:
Confidentiality alludes to shielding data from being gotten to by unapproved parties. All in all, solitary the individuals who are approved to do so can access delicate information. Imagine your bank records, You ought to have the option to get to them obviously, and representatives at the bank who are assisting you with an exchange ought to have the option to get to them, yet nobody else ought to. An inability to keep up Confidentiality implies that somebody who shouldn't have access has figured out how to get it, through deliberate act or coincidentally. Such a disappointment of Confidentiality, normally known as a breach can't be helped. When the secret has been uncovered, it is highly unlikely to un-uncover it.
Assuming your bank records are posted on a public site, everybody can realize your bank account number, balance, and so forth, and that data can't be eradicated from their brains, papers, PCs, and different spots. Virtually all the significant security occurrences reported in the media today include loss of Confidentiality.
Thus, in summary, a breach of Confidentiality implies that somebody accesses data who shouldn't be permitted to.
Write a function called is_even that takes one parameter and returns a boolean value. It should return True if the argument is even; it should return False otherwise.
The is_even function should not print anything out or return a number. It should only take in a number and return a boolean.
Note: Be sure to include comments for all functions that you use or create.
For example, if you made a call like
is_even_number = is_even(4)
is_even_number should have the value True.
Once you’ve written this function, write a program that asks the user for integers and prints whether the number they entered is even or odd using your is_even function. You should let the user keep entering numbers until they enter the SENTINEL value.
Here is a sample run of the program:
Enter a number: 5
Odd
Enter a number 42
Even
Enter a number: -6
Even
Enter a number: 0
Done!
(CODEHS, PYTHON)
def is_even_number(n):
return True if n % 2 == 0 else False
while True:
number = int(input("Enter a number: "))
if number == 0:
break
else:
if is_even_number(number):
print("Even")
else:
print("Odd")
