Stage 2

2. Look for the problem: inefficiency

The inefficiency is that it takes so many statements to display the products!

Tony’s Grossery is a small store.

How about a big supermarket? They might have 25,000 products so your program would have 25,000 lines just to display all the products!

hint

the task suggests you add a loop

you are told to check out the CodeClips

there are 2 interesting clips:

size of an array

arraySize = len(nameOfArray)

the length of an array means the number of elements

an array of length 10 would have element positions 0-9

the first element is 0, the last element is 9

traversing an array

# prints out each element of array

for i in range (0, len(nameOfArray), 1):

print(nameOfArray[i])

# end of loop

You should now

think carefully how you can use the loop code

what changes you will make

carefully go ahead and make the changes
