Values of each bar is not showing at the right spot (Matplotlib)

The value of each bar is not showing at each bar. And, also only one type of bars is showing. Where should I do some adjustments? 

import numpy as np
import matplotlib.pyplot as plt

a = [25, 30, 20]
b = [30, 20, 27]
c = [30, 25, 37]
d = [25, 40, 20]

x_ticks = ['Type 1', 'Type 2', 'Type 3']
y = [a, b, c, d]
index = np.arange(3)
plt.xticks(index + .3, x_ticks)

plt.bar(index + 0.00, a, color ='r', width = 0.22)
plt.bar(index + 0.20, b, color ='g', width = 0.22)
plt.bar(index + 0.40, c, color ='b', width = 0.22)
plt.bar(index + 0.60, d, color ='k', width = 0.22)

for a, b in enumerate(y):
    plt.text(a, b, str(b))

plt.show()

You need two loops to annotate the bars, one to loop over the types and one to loop over the subgroups.

for i,s in enumerate(y):
    for j, t in enumerate(s):
        plt.text(j+i*.2, t, str(t), ha="center")
