Python rephactor

1. Write code that swaps the first and last elements in a list called my_list. Assume that the list has already been created and contains at least one element.

2.Write code that creates a Python set containing each unique character in a string named my_string. For example, if the string is 'hello', the set would be {'h', 'e', 'l', 'o'} (in any order). Assign the set to a variable named my_set. Assume that my_string has already been initialized.

Answers

Answer 1

1.

my_list = ([1,2,3,4,5])

h = my_list[-1]

my_list[-1] = my_list[0]

my_list[0] = h

print(my_list)

2.

my_string = "hello"

my_set = set(my_string)

print(my_set)

Answer 2

The list has already been created and contains one element. The python set of my string has been already initiated.

What is python set?

Python set is defined as a data type for unordered collections that is iterable, changeable, and lacks duplication of elements. There are essentially two sorts of sets in Python. the frozenset and the set. Whether the frozenset is changeable or not depends on the set type. On a set, we can use add(), remove(), and other operations of this nature; however, frozenset does not support these actions.

The program is

your list = ([1,2,3,4,5])

my list[-1] = h

MyList[-1] equals MyList[0]

h print(my list, "my list");

"hello" is my string

set(my string) my set

print(my set)

Thus, the list has already been created and contains one element. The python set of my string has been already initiated.

D. uses port numbers to optimize the transmission of streaming media.

Answers

Answer:

A. precomputes the most efficient route and uses it to ensure rapid packet delivery.

Explanation:

In simple words, what Internet routing means is a process where a router decides which path data packets should follow that are more efficient in delivering the packets across computers.

For example, we can liken the process to the duties of a tour guide in a museum or large building in directing visiting guests who came to explore the museum.

Answers

Answer:

D) A comment line begins with #

Explanation:

Comments are used in programming to explain what a line or block of code is doing.

It helps the programmer easily remember what their code was about when they come back to it having left it for a while.

Also comments help other programmers understand code written by one programmer.

A comment or an in-line comment usually begins with #. That way the computer skips it and doesn't regard it as a line of code.

Answer: D. A comment line begins with #.

Explanation:

In the text, it stated, "The easiest way to add a comment is to start the line with the pound sign (#)."

(Comments are notes that allow you to write anything without affecting the code itself. Comments can be utilized to indicate when and how you later changed a program, and provide a description of the changes.)

Python - Functions

Advertisements

A function is a block of orgaof code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree ofAdvertisement

As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions. These functions are called user-defined functions.

Defining a Function

You can define functions to provide the required functionality. Here are simple rules to define a function in Python.

Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ).

Any input parameters or arguments should be placed within these parentheses. You can also define parameters inside these parentheses.

The first statement of a function can be an optional statement - the documentation string of the function or docstring.

The code block within every function starts with a colon (:) and is indented.

The statement return [expression] exits a function, optionally passing back an expression to the caller. A return statement with no arguments is the same as return None.

Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements and then deque elements. Which indices of the internal array elements hold the remaining elements? a) 0 to 2 b) 7 to 9 c) 2 to 4 d) 1 to 3

Answers

Full question:

Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements and then deque 2 elements. Which indices of the internal array elements hold the remaining elements? a) 0 to 2 b) 7 to 9 c) 2 to 4 d) 1 to 3

Answer and Explanation:

If you instantiate a capacity of 10 for the queue, you have the queue a capacity of not more than 10 values.

To enqueue means to add an element to the array(if it's not full, n<10)

To dequeue means to delete an element from the array or queue(if n! =0)

From the question, for example:

We create a queue of capacity 10:

Queue q(10);

We add elements/enqueue 5 elements to the queue :

q.queueEnqueue(10);

q.queueEnqueue(5);

q.queueEnqueue(8);

q.queueEnqueue(9);

q.queueEnqueue(2);

If we print this out:

q. queueDisplay()

We would get:

10, 5, 8, 9, 2

We remove elements/dequeue 2 elements from the queue :

q. queuedequeue();

q. queuedequeue();

We print it out:

q. queueDisplay()

8 ,9, 2

We observe that deletion/dequeue starts from the front/first index.

We are left with indices 2, 3, 4 or 2 to 4

Note: the above methods/ functions and objects used are merely for example purposes. The queue uses a floating front design approach.

In fact, a single-cycle or single-clock processor cannot use a resource more than once.

You probably shouldn’t rely on a computer 100% because it’s essentially important to know how things work on your own rather than depending on a computer all the time. While it can be a good thing. Like cashiers can print out a receipt rather than writing it out and consuming more time.

If an app asks for a user's age, it may be because the app requires a user to be over a certain age to use some of the services it provides. Write a function called checkAge that takes one parameter of type String. The function should try to convert this parameter into an Int value and then check if the user is over 18 years old. If he/she is old enough, print "Welcome!", otherwise print "Sorry, but you aren't old enough to use our app." If the String parameter cannot be converted into an Int value, print "Sorry, something went wrong. Can you please re-enter your age?" Call the function and pass in userInputAge below as the single parameter. Then call the function and pass in a string that can be converted to an integer.
Go back and update your function to return the age as an integer. Will your function always return a value? Make sure your return type accurately reflects this. Call the function and print the return value.
func checkage(age: String)->Int?

if let age_type = Int(age)

}
}
else {
return "Sorry, something went wrong. Can you please re-enter your age?"
}
return age_type
}

Answers

Answer and Explanation:

Here the programming language swift is being used. There is a slight error in the program shown above:

var userInputAge=9

func checkage(age: String)->int?

{

if let age_type = Int(age)

{

if age_type > 18 {

return "Welcome!"

}

else if age_type < 18 {

return"Sorry, but you aren't old enough to use our app."

}

}

else {

return "Sorry, something went wrong. Can you please re-enter your age?"

}

return age_type

}

The program should be revised :

func checkage(age: int?)->String

{

if let age_type = Int(age)

{

if age_type > 18 {

return "Welcome!"

}

else if age_type < 18 {

return"Sorry, but you aren't old enough to use our app."

}

}

else {

return "Sorry, something went wrong. Can you please re-enter your age?"

}

return age_type

}

We call the functions :

checkage(userInputAge)

checkage("15")

Note: we revised the program for errors in the first line of the code where the int optional parameter(int?) was supposed to be used instead of the String parameter in the function. We then called the function using the userInputAge variable defined as the parameter and then we now also used a String as the parameter for calling the function the second time.

Answer:

def checkage(age: "String")->int:

   if age >= 18:

       return "Welcome!"

   return "Sorry, but you aren't old enough to use our app."

   

for _ in iter(list,0):

   myage = int(input("Please enter your age: "))

   if myage is int(myage):

       result = checkage(myage)

       print(result)

       break

   print("Sorry, something went wrong. Enter integer value as age.")

   

Explanation:

The python code above lets the user input the age value for continuous comparison. If the age is an integer, it checks to know if the age is greater than 18 or not. If yes, it returns "Welcome!" else "Sorry, but you aren't old enough to use our app". But if the age is not an integer, it displays the message "Sorry, something went wrong. Can you please re-enter your age?" then prompts the user again for the age.

Note: the ': "String" ' and "->int" is for documentation purposes. They are used to describe the type of parameters (for later) and return value (the former).

Consider sending a 2400-byte datagram into a link that has an MTU of 700 bytes. Suppose the original datagram is stamped with the identification number 422. How many fragments are generated

Answers

Answer:

4

Explanation:

Given the following data

Datagram = 2400 bytes

The minimum length of an IP header = 20

Maximum Transmission Unit - MTU = 700

The original datagram is stamped with the identification number = 422

Formula = The required number of fragments = ( Datagram - IP Header) ÷ (MTU - IP Header)

= (2400 - 20) ÷ (700 - 20)

= 2380 ÷ 680

= 3.5 ≈ 4

Hence, in this case, the correct number of fragment generated is 4.

Which role will grant a delegate read-only access to a particular workspace within a user’s Outlook mailbox?
Author
Editor
Contributor
Reviewer

Answers

The role that will grant a delegate read-only access to a particular workspace within a user's Outlook mailbox is the "Reviewer" role.

In Outlook, delegates are individuals who are granted permission to access and manage another user's mailbox on their behalf. When assigning delegate permissions, different roles can be assigned to control the level of access the delegate has.

The "Reviewer" role specifically provides read-only access to the specified workspace within the user's mailbox. Delegates with this role can view the content, including emails, calendar events, and other items, but they cannot make any changes or modifications.

On the other hand, the "Author" role grants read and write access, allowing delegates to create, modify, and delete items within the designated workspace. The "Editor" role also provides read and write access but includes additional privileges such as creating subfolders and managing permissions.

The "Contributor" role allows delegates to create items within the workspace, but they cannot view items created by others. It provides a limited level of access compared to the "Reviewer" role.

Therefore, if a delegate needs read-only access to a particular workspace within a user's Outlook mailbox, the "Reviewer" role should be assigned.

A dietician obtains the amounts of sugar (incentigrams) from 100 centigrams (or 1 gram) in each of 10 differentcereals, including Cheerios, Corn Flakes, Fruit Loops, and 7others. These values are listed below. Is thestandard deviation of those values likely to be a good estimate ofthe standard deviation of the amounts of sugar in each gram ofcereal consumbed by the population of all Americans who eatcereal? Why or why not? 3, 24, 30, 47, 43, 7, 47, 13, 44, 39 Find the range, variance, standard deviation
