Part 1

The volume of a sphere is 4/3πr³, where π has the value of "pi" given as 3.141592653589793. Write a function called print_volume (r) that takes an argument for the radius of the sphere, and prints the volume of the sphere.

Call your print_volume function three times with different values for radius.

Include all of the following in your Learning Journal:

• The code for your print_volume function.
• The inputs and outputs to three calls of your print_volume

REQUIREMENTS

Submit your Python script file in the posting of your assignment. Your Python script should be either a .txt file or a .py file.

You must execute your script and paste the output produced into a document that you will submit along with your Python script.

It is very helpful if you print a placeholder between the printing of 9 lines and the printing of 25 lines. It will make your output easier to read for your peer assessors. A placeholder can be output such as “Printing nine lines” or “Calling clearScreen()”.

The following items will be used in the grading rubric for this assignment. Make sure that you have addressed each item in your assignment.

• Does the assignment implement new_line, three_lines, nine_lines, and clear_screen functions, as well as a main section of the program which calls the functions?
• Does the assignment demonstrate the use of nested function calls?

Using the IDLE development environment, create a Python script named tryme4.py. (Note: an alternative to IDLE is to use a free account on the pythonanywhere website: https://www.pythonanywhere.com/)

IDLE has both an interactive mode and a script mode. You must use the script mode to develop your script. Your script must use meaningful variable names and have comments that describe what is happening in your script. Comments may describe the assignment of a value to a variable, a computation and the assignment of the result to a variable, or the display of the result.

Write a function in this file called nine_lines that uses the function three_lines (provided below) to print a total of nine lines.

TO BE CONTINUE...

Write a python program that prompts the user to enter a few details: fullname, age, job, country and salary which are going to be included in an html file. 

 In a python module, define two functions:

• 1. A function that finds the number of words contained in a text file. 
• 2. A function that finds the number of occurrences of a given word in a given file. 
• • In another file, use these functions by asking the user about the name of the file and the word he/she wants to search for. 

Given a string, write a program to return the sum and average of the numbers that appear in the string, ignoring all other characters.Input

The input will be a single line containing a string.Output

The output should contain the sum and average of the numbers that appear in the string.

Note: Round the average value to two decimal places.Explanation

For example, if the given string is "I am 25 years and 10 months old", the numbers are 25, 10. Your code should print the sum of the numbers(35) and the average of the numbers(17.5) in the new line.

Sample Input 1

I am 25 years and 10 months old

Sample Output 1

35

17.5

Ordered Matrix

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.Input

The first line of input will contain two space-separated integers, denoting the M and N.

The next M following lines will contain N space-separated integers, denoting the elements of each list.Output

The output should be M lines containing the ordered matrix.

Note: There is a space at the end of each line.Explanation

For example, if the given M is 3 and N is 3, read the inputs in the next three lines if the numbers given in the next three lines are the following.

1 20 3
30 10 2
5 11 15

By ordering all the elements of the matrix in increasing order, the ordered matrix should be

1 2 3
5 10 11
15 20 30

Sample Input 1

3 3

1 20 3

30 10 2

5 11 15

Sample Output 1

1 2 3

5 10 11

15 20 30

Smallest Missing Number

Given a list of numbers, write a program to print the smallest positive integer missing in the given numbers.Input

The input will be a single line containing numbers separated by space.Output

The output should be a single line containing the smallest missing number from given numbers.Explanation

For example, if the input numbers are 3, 1, 2, 5, 3, 7, 7.

The number 1, 2, 3 are present. But the number 4 is not. So 4 is the smallest positive integers that is missing from the given numbers.

Sample Input 1

3 1 2 5 3 7 7

Sample Output 1

4

Sample Input 2

5 5 2 3 1 8 8 4

Sample Output 2

6

Number to English Words

Write a program to convert a non-negative integer

N to its English words representation.Input

The input will be a single line containing an integer

N. Note: The input number will not be greater than 10¹⁰.Output

The output should be a single line containing the representation of the English words of number

N. See the sample input and output for the English words of numbers in places.Explanation

For example, if the given number is 123, your code should print the English words representation, which is

One Hundred Twenty Three

Sample Input 1

123

Sample Output 1

One Hundred Twenty Three

Sample Input 2

10005

Sample Output 2

Ten Thousand Five

Sample Input 3

Sample Output 3

One Billion Two Hundred Thirty Four Million Five Hundred Sixty Seven Thousand Eight Hundred Ninety One

Area of Rectangle

Given an MxN matrix filled with

X's and O's, find the largest rectangle containing only X's and return its area. If there are no Xs in the entire matrix print 0.Input

The first line of input will be containing two space-separated integers, denoting M and N.

The next M lines will contain N space-separated integers, denoting the elements of the matrix.

Output

The output should be a single line containing the area of the maximum rectangle.

Explanation

For example, if the given M, N and elements of matrix are as the following

4 5

X O X O O

X O X X X

X X X X X

X O O X O

The matrix from indices (1, 2) to (2, 4) has the maximum rectangle with

X. So the output should be the area of the maximum rectangle with X, which is 6.
