Implement function easyCrypto() that takes as input a string and prints its encryption
defined as follows: Every character at an odd position i in the alphabet will be
encrypted with the character at position i+1, and every character at an even position i
will be encrypted with the character at position i 1. In other words, ‘a’ is encrypted with
‘b’, ‘b’ with ‘a’, ‘c’ with ‘d’, ‘d’ with ‘c’, and so on. Lowercase characters should remain
lowercase, and uppercase characters should remain uppercase.
>>> easyCrypto('abc')
bad
>>> easyCrypto('Z00')
YPP
Answer:
The program written in python is as follows;
import string
def easyCrypto(inputstring):
for i in range(len(inputstring)):
try:
ind = string.ascii_lowercase.index(inputstring[i])
pos = ind+1
if pos%2 == 0:
print(string.ascii_lowercase[ind-1],end="")
else:
print(string.ascii_lowercase[ind+1],end="")
except:
ind = string.ascii_uppercase.index(inputstring[i])
pos = ind+1
if pos%2 == 0:
print(string.ascii_uppercase[ind-1],end="")
else:
print(string.ascii_uppercase[ind+1],end="")
anystring = input("Enter a string: ")
easyCrypto(anystring)
Explanation:
The first line imports the string module into the program
import string
The functipn easyCrypto() starts here
def easyCrypto(inputstring):
This line iterates through each character in the input string
for i in range(len(inputstring)):
The try except handles the error in the program
try:
This line gets the index of the current character (lower case)
ind = string.ascii_lowercase.index(inputstring[i])
This line adds 1 to the index
pos = ind+1
This line checks if the character is at even position
if pos%2 == 0:
If yes, it returns the alphabet before it
print(string.ascii_lowercase[ind-1],end="")
else:
It returns the alphabet after it, if otherwise
print(string.ascii_lowercase[ind+1],end="")
The except block does the same thing as the try block, but it handles uppercase letters
except:
ind = string.ascii_uppercase.index(inputstring[i])
pos = ind+1
if pos%2 == 0:
print(string.ascii_uppercase[ind-1],end="")
else:
print(string.ascii_uppercase[ind+1],end="")
The main starts here
This line prompts user for input
anystring = input("Enter a string: ")
This line calls the easyCrypto() function
easyCrypto(anystring)

You are getting ready to write the project management plan and know you need to consider elements such as policies, rules, systems, relationships, and norms in the organization. Which of the following is not true? A These describe the authority level of workers, fair payment practices, communication channels, and the like. B This describes organizational governance framework. C This describes management elements. D This is part of the EEF input to this process.
Answer:
A. These describe the authority level of workers, fair payment practices, communication channels, and the like.
Explanation:
As seen in the question above, you have been asked to write the project management plan and know that you need to consider elements such as policies, rules, systems, relationships and standards in the organization. These elements are part of EEF's entry into this process, in addition they are fundamental and indispensable for the description not only of the organizational governance structure, but also describe the management elements that will be adopted and used.
However, there is no way to use them to describe the level of authority of workers, fair payment practices, communication channels and the like, as this is not the function of this.

Discuss the differences between dimensionality reduction based on aggregation and dimensionality reduction based on techniques such as PCA and SVD.
Answer:
Following are the difference to this question can be defined as follows:
Explanation:
In terms of projections of information into a reduced dimension group, we can consider the dimension structure of PCA and SVD technologies. In cases of a change in the length, based on consolidation, there's also a unit with dimensions. When we consider that the days have been aggregated by days or the trade of a commodity can be aggregated to both the area of the dimension, accumulation can be seen with a variance of dimension.Dimensionality reduction based on aggregation involves selection of important character and variable from a large variable and dimensionality reduction based on techniques with the use of PCA and SVD.
What is dimensionality?Dimensionality involves reducing features that have been written or identified or constructing less features from a pool of important features.
Principal components analysis(PCA) and Single value decomposition(SVD) is a form or analysis that can be used to reduce some character that are not important to an information and can also help to select important variables from among many variables.
Therefore, dimensionality reduction based on aggregation involves selection of important character and variable from a large variable and dimensionality reduction based on techniques with PCA and SVD.

Without data compression, and focusing only on the data itself without any overhead, what transmission rate is required to send 30 frames per second of gray-scale images with resolution 1280 x 1024?
Answer:
315 Mbps
Explanation:
Given data :
30 frames per second
resolution = 1280 * 1024
what transmission rate is required can be calculated as
frames per second = rendered frames / number of seconds passed
30 = 30 / 1
Transmission rate = the rate at which the images are transmitted from source to destination =315 Mbps without data compression
The compare_strings function is supposed to compare just the alphanumeric content of two strings, ignoring upper vs lower case and punctuation. But something is not working. Fill in the code to try to find the problems, then fix the problems.
import re
def compare_strings(string1, string2):
#Convert both strings to lowercase
#and remove leading and trailing blanks
string1 = string1.lower().strip()
string2 = string2.lower().strip()
#Ignore punctuation
punctuation = r"[.?!,;:-']"
string1 = re.sub(punctuation, r"", string1)
string2 = re.sub(punctuation, r"", string2)
#DEBUG CODE GOES HERE
print(___)
return string1 == string2
print(compare_strings("Have a Great Day!", "Have a great day?")) # True
print(compare_strings("It's raining again.", "its raining, again")) # True
print(compare_strings("Learn to count: 1, 2, 3.", "Learn to count: one, two, three.")) # False
print(compare_strings("They found some body.", "They found somebody.")) # False
Answer:
There is a problem in the given code in the following statement:
Problem:
punctuation = r"[.?!,;:-']"
This produces the following error:
Error:
bad character range
Fix:
The hyphen - should be placed at the start or end of punctuation characters. Here the role of hyphen is to determine the range of characters. Another way is to escape the hyphen - using using backslash \ symbol.
So the above statement becomes:
punctuation = r"[-.?!,;:']"
You can also do this:
punctuation = r"[.?!,;:'-]"
You can also change this statement as:
punctuation = r"[.?!,;:\-']"
Explanation:
The complete program is as follows. I have added a print statement print('string1:',string1,'\nstring2:',string2) that prints the string1 and string2 followed by return string1 == string2 which either returns true or false. However you can omit this print('string1:',string1,'\nstring2:',string2) statement and the output will just display either true or false
import re #to use regular expressions
def compare_strings(string1, string2): #function compare_strings that takes two strings as argument and compares them

string2 = string2.lower().strip() # converts the string1 characters to lowercase using lower() method and removes trailing blanks
punctuation = r"[-.?!,;:']" #regular expression for punctuation characters
string1 = re.sub(punctuation, r"", string1) # specifies RE pattern i.e. punctuation in the 1st argument, new string r in 2nd argument, and a string to be handle i.e. string1 in the 3rd argument
string2 = re.sub(punctuation, r"", string2) # same as above statement but works on string2 as 3rd argument
print('string1:',string1,'\nstring2:',string2) #prints both the strings separated with a new line
return string1 == string2 # compares strings and returns true if they matched else false
#function calls to test the working of the above function compare_strings
print(compare_strings("Have a Great Day!","Have a great day?")) # True
print(compare_strings("It's raining again.","its raining, again")) # True
print(compare_strings("Learn to count: 1, 2, 3.","Learn to count: one, two, three.")) # False
print(compare_strings("They found some body.","They found somebody.")) # False
The screenshot of the program along with its output is attached.

What is industry 4.0 -automation revolution-, what is your opinion about the direction this revolution is taking the industry in, and discuss the fate of unskilled and semi-skilled workers affected by industry 4.0.
Answer:
Find the explanation below.
Explanation:
1. Industry 4.0 -automation revolution is a term first used in Germany in 2011 to describe the fourth generation of the industrial revolution. It is the incorporation of digitalized procedures that use smart technology that can work in real-time to industrial production. This means that the machines used in production can independently interact between themselves to accomplish tasks that would otherwise have needed human involvement.
2. My opinion regarding this industrial revolution is that it is a welcome development for businesses because it will help them execute projects at faster rates and limit some working expenses.
3. Unskilled and Semi-skilled workers will be badly affected by this revolution because tasks ordinarily performed by them would be mostly taken over by these machines. This means that companies would most likely lay off these workers whose jobs would now be performed by machines. Job regulation agencies would do well to seek ways to intervene for this group of workers. They may also have to improve their skills if they want to remain relevant to their jobs.
The revolution, however, would be favorable for high-skilled workers because they would be needed to perform jobs such as the maintenance and programming of these machines.
An app developer is shopping for a cloud service that will allow him to build code, store information in a database and serve his application from a single place. What type of cloud service is he looking for?
Answer:
Platform as a Service (PaaS).
Explanation:
In this scenario, an app developer is shopping for a cloud service that will allow him to build code, store information in a database and serve his application from a single place. The type of cloud service he is looking for is a platform as a service (PaaS).
In Computer science, Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.
The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.
Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).
Hence, the advantage of the Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.
These are the different types of Platform as a Service;
1. Private PaaS.
2. Public PaaS.
3. Hybrid PaaS.
4. Mobile PaaS.
5. Communications PaaS.
6. Open PaaS.
The software developers can choose any of the aforementioned types of PaaS that is suitable, effective and efficient for their applications development. Some examples of PaaS providers are Google, Microsoft, IBM, Oracle etc.

print("Year ", count, " Salary: ", StartingSal*((1+AnnualIncrease)**(count-1)))
Explanation:
This program prompts the user to enter starting salary, percentage increase in salary per year and number of years.
The for loop has range function which is used to specify how many times the salaries are going to be calculated for the number of years entered. It starts from 1 and ends after Years+1 means one value more than the year to display 10 too when user inputs 10 days.
The year and corresponding salary is displayed in output. At every iteration the starting salary is multiplied by annual percentage increase input by user. Here count is used to count the number of salaries per year, count-1 means it will start from 30000.
1 #Write a function called phonebook that takes two lists as
2 #input:
3 #
4 # - names, a list of names as strings
5 # - numbers, a list of phone numbers as strings
6 #
7 #phonebook() should take these two lists and create a
8 #dictionary that maps each name to its phone number. For
9 #example, the first name in names should become a key in
10 #the dictionary, and the first number in numbers should
11 #become the value corresponding to the first name. Then, it
12 #should return the dictionary that results.
13 #
14 #Hint: Because you're mapping the first name with the first
15 #number, the second name with the second number, etc., you do
16#not need two loops. For a similar exercise, check back on
17 #Coding Problem 4.3.3, the Scantron grading problem.

19 #You may assume that the two lists have the same number of #items: there will be no names without numbers or numbers

Answer:
I am writing a Python program.
def phonebook(names, numbers): #method phonebook that takes two parameters i.e a list of names and a list of phone numbers
dict={} #creates a dictionary
for x in range(len(names)): # loop through the names
dict[names[x]]=numbers[x] #maps each name to its phone number
return dict #return dictionary in key:value form i.e. name:number
#in order to check the working of this function, provide the names and numbers list and call the function as following:
names = ['Jackie', 'Joshua', 'Marguerite']
numbers = ['404-555-1234', '678-555-5678', '770-555-9012']
print(phonebook(names, numbers))
Explanation:
The program has a function phonebook() that takes two parameters, name which is a list of names and numbers that is a list of phone numbers.
It then creates a dictionary. An empty dictionary is created using curly brackets. A dictionary A dictionary is used here to maps a names (keys) phone numbers (values) in order to create an unordered list of names and corresponding numbers.
for x in range(len(names)):
The above statement has a for loop and two methods i.e. range() and len()
len method is used to return the length of the names and range method returns sequence of numbers just to iterate as an index and this loops keeps iterating until x exceeds the length of names.
dict[names[x]]=numbers[x]
The above statement maps each name to its phone number by mapping the first name with the first umber, the second name with the second number and so on. This mapping is done using x which acts like an index here to map first name to first number and so on. For example dict[names[1]]=numbers[1] will map the name (element) at 1st index of the list to the number (element) at 1st index.
return dict retursn the dictionary and the format of dictionary is key:value where key is the name and value is the corresponding number.
