Solve the following python programming problem given the following code:
def execute(self, image_config, mandelbrot_config, chunk) : 
    'Returns the number of iterations before the computation "escapes".

        Given the real and imaginary parts of a complex number, determine if it
        is a candidate for membership in the mandelbrot set given a fixed
        number of iterations.
        ' 
    def mandelbrot(x, y, max_iters) : 
        c = complex (x, y) 
        z = 0j 
        for i in compat_range (max_iters) : 
            z = ((z * z) + c) 
            if (((z.real * z.real) + (z.imag * z.imag)) >= 4) : 
                return i 
return max_iters 
(min_x, max_x, min_y, max_y, max_iters) = mandelbrot_config 
    (height, width) = image_config ['size'] 
    pixel_size_x = ((max_x - min_x) / width) 
    pixel_size_y = ((max_y - min_y) / height) 
    block = [] 
    for y in compat_range (chunk [0], min_y [1]) : 
        row = [] 
        imag = (min_y + (y * pixel_size_y)) 
        for x in compat_range (0, width) : 
            real = (min_x + (x * pixel_size_x)) 
            row.append (mandelbrot (real, imag, max_iters)) 
block.append (row) 
return block 

    
    

    Fix the buggy line: for y in compat_range (chunk [0], min_y [1]) :
assistant
#Here is Python code to determine if it
.

for y in compat_range (chunk [0], chunk [1]) :
