Student Generated Code Assignments Option 1: Write a program that will read in 3 grades from the keyboard and will print the ave

rage (to 2 decimal places) of those grades to the screen. It should include good prompts and labeled output. Use the examples from the earlier labs to help you. You will want to begin with a design. The Lesson Set 1 Pre-lab Reading Assignment gave an introduction for a design similar to this problem. Notice in the sample run that the answer is stored in fixed point notation with two decimal points of precision. Sample run: Option 2: The Woody furniture company sells the following three styles of chairs: Style Price Per Chair American Colonial $ 85.00 Modern $ 57.50 French Classical $127.75 Write a program that will input the amount of chairs sold for each style. It will print the total dollar sales of each style as well as the total sales of all chairs in fixed point notation with two decimal places.
Sample run:
Please input the first grade 97
Please Input the second grade 98.3
Please Input the third grade 95
The average of the three grades is 96.77

In python:

first_grade = float(input("Please input the first grade "))

second_grade = float(input("Please input the second grade "))

third_grade = float(input("Please input the third grade "))

print("The average of the three grades is {}".format( round((first_grade + second_grade + third_grade) / 3,2)))

What is the output of the code below assuming that global variable x has value 2 and global y has value 3? def f1(): return "ab"
Lostsunrise [7]

Answer:

ababababab

Explanation:

The code above is written in python and python uses indentation .So let me rephrase the code accordingly and explain what the code really do.

Note x and y is a global variable which can be used by any of the function declared.  According to the question x and y are 2 and 3 respectively

The first block of code describes a function f1 without any argument but the code should return the string "ab"

def f1():

      return "ab"

The second block of code defines a function f2 and returns the value of f1 multiply by x. This means you are multiplying the string "ab" by 2 which will be equals to abab

def f2():

           return f1() * x

The third block of code declared a function f3 and returns the sum of  f2 and product of f1 and y. using PEMDAS principle the multiplication aspect will be solved first so, ab × 3 = ababab, then we add it to f2  . ababab + abab = ababababab.

def f3():

        return f2() + f1() * y

Finally, we print the function f3 value to get ababababab

print(f3())

If you run the code on your IDE like below you will get  ababababab

x = 2

y = 3

def f1():

      return "ab"  

def f2():

      return f1() * x  

def f3():  

      return f2() + f1() * y  

print(f3())

Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent singl
victus00 [196]

Answer:

following are the program to the given question:

Program:

x = 0#defining an integer variable that holds a value

if x < 0:#defining if that checks x less than 0

   print("This number ",  x, " is negative.")#print value with the message

else:#defining else block

   if x > 0:#defining if that checks x value greater than 0

       print(x, " is positive")#print value with message

   else:#defining else block

       print(x, " is 0")#print value with message

if x < 0:#defining another if that checks x less than 0

   print("This number ",  x, " is negative.")

elif (x > 0):#defining elif block that check x value greater than 0

   print(x, " is positive")#print value with message

else:#defining else block

   print(x, " is 0")#print value with message

Output:

Please find the attachment file.

Explanation:

In this code, an x variable is defined which holds a value that is "0", in the next step nested conditional statement has used that checks the x variable value and uses the print method that compares the value and prints its value with the message.

In another conditional statement, it uses if that checks x value less than 0 and print value with the negative message.

In the elif block, it checks x value that is greater than 0 and prints the value with the positive message, and in the else block it will print the message that is 0.
