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 xs sign).

The hints given above, create a Pseudocode to calculate an average of a given array of number and output all numbers that are higher than the average by more than 20%.
