Python is one of the most popular programming languages and it is a #1 language for data analysis, which could be a part of MIS or a task by itself.

Traditionally programming is divided into core functions (or computing) and interfaces.

Core functions can be seen as a box (programming module) that accepts certain input, compute something, and provide the output. The interface modules would be responsible for collecting input and presenting the output.

As we learned, data can be stored in variables, or collections like lists (or arrays). The idea behind the list is that a single name will be used along with the index to store multiple values.

Let a be a Python list, then we can declare a list with values as:

a = [2, 4, 3, 10, 33]

 

Standard functions can be used to calculate the sum or the length (number of elements) of a list:

sum(a)
len(a)

 

One of the most common operations with lists is iteration. Then a code can be repeatedly applied to each element of the list. For example, the code bellow will iterate through the list and print each element of the list

for element in a:

      print (element)

 

As you can see print() will output the values of .

A part of the code can be written to be executed under certain condition.  Then an if statement should be used. For example, the code below calculates an absolute value of a variable:

if x < 0:

            x = -x

(If x is less than zero assign -x to x (or invert x's sign).

 

Directions 

 

Using the core concepts of Python language, and the hints given above, creatte a Python program to calculate an average of a given array of number and output all numbers that are higher than the average by more than 20%.

Use Python comments (# at the beginning of a line) to explain the purpose of each part of the code. Upload your code as a text file to the assignment dropbox.

 

The professor provided this as help:

 

Description: This program will take in a given array of numbers, find the average and print it, then find the number that is 20% greater than the average and print it, and then print all numbers that are greater than that number.

#This is the hard coded array that the program will use. We assign the array to variable a.

a = [10, 11, 12, 13, 14, 15, 16, 17, 18, 20]

#We will now add up all the numbers in the array and divide by the number of numbers that are in the array and assign to variable b.

b = sum(a)/len(a)

#We print the average number of the array.

print ("The average of the array is: %s" % b)

#We now find what number is 20% more than the average in the array and assign to variable c.

c = (b*.20) + b

#We print this number.

print ("The average of the array plus 20 percent is: %s" % c)

#We creatte an empty array and call it y. This array will be used to hold all numbers greater than c.

y = []

#Loop through array a and assign to variable x.

for x in a:

#If x is greater than c.

    if x > c:

#If the above is true, add to the array y.

       y.append(x)

#Print the numbers that are in array y.

print ("The numbers in the array greater than the average plus 20 percent are: %s" % y)

 

Please read through and help me come up with the code and code with comments. I have never done coding so please explain your answer if you can. please show me what code to input (I'm supposed to use pythonfiddle.com) to answer the question.
