Change ticks of y-axis in python

I want to change y axis ticks in python. I am using the code

import pylab as plt
y1 = [0,1,2,...10]
y2 = [90,40,65,12,....]
labels = [0.30,0.29,0.28,....]
plt.plot(y1)
plt.plot(y2,'r')
plt.yticks(y1, labels)
plt.yticks(y2, labels)
plt.show()

But all the y axis label appear at one place on top of one another

Borrowing heavily from this example, the code below demonstrates one possible way to have two plots on one figure. 

import pylab as plt

fig, ax1 = plt.subplots()
y1 = [0,1,2,3,4,5,6,7,8,9,10]

labels = [0.30,0.29,0.28,0.27,0.26,0.25,0.24,0.23,0.22,0.21,0.20]
ax1.plot(labels, y1, 'b-')

ax1.set_xlabel('labels')
# Make the y-axis label, ticks and tick labels match the line color.
ax1.set_ylabel('y1', color='b', rotation="horizontal")
ax1.tick_params('y', colors='b')

ax2 = ax1.twinx()
y2 = [90,40,65,12,23,43,54,13,42,53,63]
ax2.plot(labels, y2, 'r-')
ax2.set_ylabel('y2', color='r', rotation="horizontal")
ax2.tick_params('y', colors='r')

fig.tight_layout()
plt.show()
