Struggling with plt.annotate command, unsure of syntax for first 'label' argument

Question

x_G = np.array([12, 210, 80, 165, 150, 272, 10, 7.5])
y_G = np.array([20.0, 40.0, 60.0, 60.0, 60, 80, 8, 20])
names_G = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H']

for x, y in zip (x_G, y_G):
    plt.annotate(names_G, (x, y), textcoords='offset points', xytext=(0, 10), ha='center')

So I know the first argument, names_G is wrong, and makes no sense but I’m unsure how to get the first label 'A', to correspond to the (12,20.0) point and so on.
If anyone could point me in the right direction, that would be great thanks.

There isn’t any problem in including the text in the zip:

for x, y, t in zip (x_G, y_G, names_G):
    plt.annotate(t, (x, y), textcoords = 'offset points', xytext=(0,10), ha='center')

As an alternative to defining your list of names manually, you may want to get a list of characters:

import string

names = string.ascii_uppercase
