Hello,
I'm writing my code into the 'vizard python editor' and sometimes it feels a bit bugged or something, now I get an error message that my class has no attribute.
I feel it has to do something with editing in vizard because in other editors I don't think i get this message.
Here's my code:
import csv
class Grid(list):

self.grid = []
self.width = width
self.height = height

col.append(Cell(x, y, self.grid))
self.grid.append(col)

return self.grid[x][y]

if (x < 0 or y < 0 or x >= self.width or y >= self.height):
return
cell = self.grid[x][y]
cluster = Cluster()
if (cell.clusterId != -1 or cell.value != landUse):
return
cell.setClusterId(clusterId)
cluster.add(cell)
self.floodFill(x-1, y, clusterId, landUse)
self.floodFill(x+1, y, clusterId, landUse)
self.floodFill(x, y-1, clusterId, landUse)
self.floodFill(x, y+1, clusterId, landUse)
def analyze(self):
freeCell = self.firstFreeCell()
clusterId = 0
while freeCell != None:
self.floodFill(freeCell.x, freeCell.y, clusterId, freeCell.value)
freeCell = self.firstFreeCell()
clusterId += 1
def printClusterId(self, clusterId):
for y in range(self.height):
for x in range(self.width):
if self.grid[x][y].clusterId == clusterId:
print 'ClusterId:', clusterId, '=>', 'Cell-coordinates:',
'(', self.grid[x][y].x, ',', self.grid[x][y].y, ')',

print "No cells with such clusterId left or the clusterId is not defined yet..."

"""the printGrid2 method can't be found or something. When I delete this method and copy/paste the printGrid method and change this copied one to printGrid2 it sometimes works and other times it doesn't. I feel it has to do something with a bug or it doesn't read the syntax right sometimes. Anyone has this problem or sees why it happens? I would be thankfull.
