Mandelbrot set in Python

[Snorku]

I was kinda in rush, that's why I bumped, sorry for that.

import matplotlib.pyplot as plt


def funkcja(c=0j, z=0 + 0j, n_max=100):
    for i in range(n_max):
        z = z * z + c
        if abs(z) > 2.0:
            T[i][j] = abs(z)
        break

k = 600
l = 600

T = [[0]*l for i in range(k)]

for i in range(k):
    for j in range(l):
        T = [(complex(-2 + i * 0.005, -1.5 + j * 0.005))]



plt.imshow(T, cmap="bone")
plt.show()

Came up before with this, still, don't really know how to excecute the numbers I need for final product. I get an error: TypeError: Image data of dtype complex128 cannot be converted to float. What do I need to change?
