# Learning objective: creating a variable sized 2D list using 2 calls to
# 'append':
#  1) First append adds an empty row to the list (line 13)
#  2) Second append adds sucessive elements to the newly created row (line 16)

aGrid = []

#Create list
for r in range (0,noRows,1):

    for c in range (0,noColumns,1):
        element = r
        aGrid[r].append(element)
#Display list

   for c in range (0,noColumns,1):
