Hide axis lines and labels in matplotlib except min/max y-label

Question

I have plot in Python matplotlib:

from matplotlib import pyplot as plt

data = [1, 5, 2, 1, 1, 4, 3, 1, 7, 8, 9, 6, 1]
plt.plot(data)

Is there any way to hide axis lines and labels except min and max y-axis label? I know about plt.axis("off"), however I would like to show first and last label on y-axis.

The current plot is on the left of the image below and desired plot on the right.

Answer 1

Here you format the borders and ticks to hide them and then set the y-ticks explicitly:

from matplotlib import pyplot as plt

data = [1, 5, 2, 1, 1, 4, 3, 1, 7, 8, 9, 6, 1]

fig, ax = plt.subplots()
ax.plot(data)
for side in ['top','right','bottom','left']:
    ax.spines[side].set_visible(False)
ax.tick_params(axis='both',which='both',labelbottom=False,bottom=False,left=False)
ax.set_yticks([min(y),max(y)])
