The `enumerate()` function is useful when we want to access both the value and
its index number, or any sequence, such as a list or string. 


For example, a list is an ordered data structure that stores each item
with its index number. Using the item’s index number, we can access or
modify its value.


The form of `enumerate()`: ``for index, value in enumerate(___)``

As a reminder: *index* - is the position of the element. In Python, we start counting indexes from 0.
  

numbers = [2, 3, 8, 5, 6, 7, 8, 11, 8]

# Printing all elements of the list with their indexes
for i, v in enumerate(numbers):
  print('Numbers[', i, '] =', v)

We start learning Python loops with the for loop. A for loop is used for iterating over a sequence. Let's go!

With the while loop, we can execute a set of statements as long as a condition is true. We are going to work with this loop and handle different problems!

A nested loop is a loop inside a loop. Sound difficult? Don't worry! We will handle this loop!
