Converting image to grayscale python

Question

Can anyone help with the code to go after for loop to convert to grayscale either by average method or weighted method

import matplotlib.pyplot
import numpy


myImage = matplotlib.pyplot.imread('flower.png')

height=myImage.shape[0]
width=myImage.shape[1]

for x in range(0, height-1):
    for y in range(0,width-1):

      INSET CODE HERE


imgplot = matplotlib.pyplot.imshow(myImage)
matplotlib.pyplot.show()

There's already been a post about this - you can either use PIL easily or create it yourself with Numpy and Matplotlib.
