# 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 = []
noRows = int(input("Number rows: "))
noColumns = int(input("Number columns: "))
#Create list
for r in range (0,noRows,1):
    aGrid.append ([])
    for c in range (0,noColumns,1):
        aGrid[r].append("*")
#Display list
for r in range (0,noRows,1):
   for c in range (0,noColumns,1):
      print(aGrid[r][c], end="")
   print()
