matplotlib - How can I change the x-axis labels in a Python plot?

Question

I have this code :

import numpy as np
import pylab as plt

a = np.array([1,2,3,4,5,6,7,8,9,10])
b = np.exp(a)
plt.plot(a,b,'.')
plt.show()

The code works fine, but I need to modify the x-axis labels of the plot. I would like the x-axis labels to be all powers of 10 according to the a axis inputs. for the example code, it would be like [10^1, 10^2, ..., 10^10].

I would appreciate any suggestions.

Thank you !

import numpy as np
import pylab as plt

a = np.array([1,2,3,4,5,6,7,8,9,10])
# this is it, but better use floats like 10.0, 
# a integer might not hold values that big
b = 10.0 ** a 
plt.plot(a,b,'.')
plt.show()
