the QUESTION IN PYTHON

Now write a program named filereader.py that reads and displays the data in friends.txt. This program should also determine and print the average age of the friends on file. That will require an accumulator and a counter. Use a while loop to process the file, print the data, and modify the accumulator and counter. Then close the file and display the average age accurate to one decimal place. See the Sample Output..
SAMPLE OUTPUT

My friend Denny is 24
My friend Penny is 28
My friend Lenny is 20
My friend Jenny is 24
Average age of friends is 24.0

1.Create full program in Java that will simulate a Rock Paper Scissors Game You will create the code so that when the program is run the user will see in the console the following: We are going to play rock paper scissors. Please choose 1 for Rock 2 for Paper or 3 for scissors. The program will have your choice which is the integer-valued typed in by the user and compChoice which will be the randomly generated value of either 1 2 or 3. You will test all the ways the user wins if he or she beats the computer using || with if and then you will check all the ways that computer could win using else if with || and lastly the only other thing that can happen would be a tie if both choices are the same for the default else. Display what was chosen and what was randomly chosen by the computer and who wins or if there is a tie. For extra credit, you can use dialog boxes and show images.

Create two classes based on the java code below. One class for the main method (named InvestmentTest) and the other is an Investment class. The InvestmentTest class has a main method and the Investment class consists of the necessary methods and fields for each investment as described below.

1.The Investment class has the following members:

a. At least six private fields (instance variables) to store an Investment name, number of shares, buying price, selling price, and buying commission and sales commission.

b. Write set and get methods to access each of the private fields

c. “InvestmentSummary” method to print Investment Information including the result of

3. Create two different objects of the investment class

4. Create an object of java.util.Scanner to input the information about each investment, one at a time form the keyboard, and track the information in the proper Investment objects by placing calls to the proper set methods for each of the two objects.

5. When invoking the InvestmentSummary method, use the get method found in the Investment class to access the private members.

How to write this Python
You are a small business owner and you have six employees. All the employees have the same pay rate, that is $12 per hour. Write a program that will ask the user to enter the number of hours worked by each employee, then display the amounts of gross pay for each employee.

1.    Get the number of worked hours for each employee and store it in a list.
2.    Use the stored value in each element to calculate the gross pay for each employee and display the amount. 
3.    Match your output format to the below sample output.

Answer should look like this

Enter the hours worked by employee 1: 20
Enter the hours worked by employee 2: 25
Enter the hours worked by employee 3: 29
Enter the hours worked by employee 4: 30
Enter the hours worked by employee 5: 20
Enter the hours worked by employee 6: 19

Enter the hourly pay rate: 12

Gross pay for employee 1: $240.00
Gross pay for employee 2: $300.00
Gross pay for employee 3: $348.00
Gross pay for employee 4: $360.00
Gross pay for employee 5: $240.00
Gross pay for employee 6: $228.00

What decimal value does the 8-bit binary number 10011110 have if:

a) it is interpreted as an unsigned number?

b) It is on a computer using signed-magnitude representation?

c) It is on a computer using one’s complement representation?

d) It is on a computer using two’s complement representation?

when the user entered a negative number, you output a message that it was not possible to take the square root of a negative number. This time you will write a Python program that asks the user to enter a non-negative number (float). If the user does enter a negative number, you will use a while loop to continue prompting the user until you get a valid number (i.e. a number >= 0). Once the user enters a valid number, you calculate and print the square root. Test your program twice, once using a negative number and once using a non-negative number.

Write a python function called HackCaesar with the following requirements:

def hack_caesar(cyphertext): ‘’’ cyphertext is a text encoded using Caesars encryption. The encryption key is unknown. The function returns the correct encryption key. Hint: Use the function we wrote was called caesar(c, key) and could encode a single character.

Write a decorator function that has the following property:

1.  The name of a decorator is uppercase and takes a function as input.

2.  The decorator has an inner function called wrapper with no input argument.

3.  The wrapper function has two local variables: original and modified.

4.  The input function argument of decorator gets assigned to the original variable inside the wrapper function and the upper case version of the input function gets assigned to the modified variable.

5.  The wrapper function returns the modified variable.

6.  The decorator returns the wrapper (per the usual of the inner functions in decorators)

7.  Write a new function called greetings that prints “Hello”.

8.  Decorate the greetings function with the uppercase decorator function.

9.  Run the program by invoking the greetings function. Record the output and include it with your code.

10. Save the decorator uppercase as a separate Python file and import it to a new file that defines the greetings function as a decorated function that simply prints the “Hello” message.

11. Generate the output by invoking the greetings function.

Q2) How thick does paper folding get? Take one sheet out of your newspaper, and fold it in half, then fold it in half again, and again, and again. Can you fold it 30 times? Pretending that you can (you probably can’t fold it more than 8 times), how thick would it be after 30 times? Assume the paper is 1/200 cm. thick. Write a program to solve this puzzle. Prompt for the number of folds and output the thickness in meters. Note : Run by pycharm

Hank & Sons is a retail seller of computers. At the end of the month, each salesperson’s commission is calculated according to the commission table in the previous question. Salespersons also need to pay a monthly admin fee based on their total monthly sales for office supply.

For example, a salesperson with $16,000 in monthly sales will earn a 12% commission minus admin fee ($1,920 - $150). Another salesperson with $20,000 in monthly sales will earn a 15% commission minus admin fee ($3,000 - $200).

Because the staff gets paid once per month, Hank & Sons allows each employee to take up to $1,500 per month in advance. When sales commissions are calculated, the amount of each employee’s advanced pay is subtracted from the commission. If any salesperson’s commission is less than the amount of this advance, he or she must reimburse Hank & Sons for the difference.

Write the pseudo code for calculating the total monthly net income for Hank & Sons sellers. The program should first ask the user to enter the salesperson’s monthly sales and the amount of advanced pay. Then draw the flowchart for your pseudo code.

This is a very simple program that will ONLY print a heading and columns of text to emulate the following information:

******Salesperson of the month******

Name: STUDENT NAME

ID: STUDENT ID

public class SalesResult {

public static void main(String[] args) {

System.out.println();

. . .

}

}

Create a Java project in Eclipse named SalesProject and add a class named SalesResult to reproduce a table like the above. In your program repeat the System.out.println(); as many times as needed.

I was wondering how to write the code to create such a table...
