About arrays

Arrays allow you to store multiple values into a single variable reference. This makes the manipulation of the data held within the array much simpler by the use of a loop.

The sample code is taken from the video.

#  index   0  1 2 3  4  5  6  7  8  9 10 11 12 13 14
scores = [40,20,1,49,34,41,35,37,46,32,5,3, 1, 6, 54]
# square brackets allow access to the array
x = 0
while x < len(scores):
	print scores[x], "index ", x
	x = x + 1

Key term

Data structure – a specific way of structuring a set of data in order to make the manipulation of that data easier.
