python single line for loops [closed]

Question

i'm using processing.py

i was following this tut (Java)

https://www.youtube.com/watch?v=H7frvcAHXps

and i'm wondering if i can use the same kind of for loop in python

for(int y = 0; y < height; y = y + cellSize):

    for(int x = 0; x < width; x = x + cellSize):

        rect(x, 0, cellSize, cellSize)

I receive an error when i try to run the code:

processing.app.SketchException: Maybe there's an unclosed paren or quote mark somewhere before this line?

I guess there's probably an easy but slightly different way to do the use the same kind of nested for loops (on a single line) in python

def drange(start, stop, step):
    """floating range

    """
    r = start
    while r < stop:
        yield r
        r += step

for y in drange(0, height, cellSize):
    for x in drange(0, width, cellSize):
        rect(x, 0, cellSize, cellSize)
