Use

ax.xaxis.set_ticks_position("top")

For example,

import numpy as np
import matplotlib.pyplot as plt

numdata = 100
t = np.linspace(0, 100, numdata)
y = 1/t**(1/2.0)

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
ax.xaxis.set_ticks_position('top')
ax.yaxis.grid(linestyle = '-', color = 'gray')
ax.invert_yaxis()
ax.plot(t, y, 'g-', linewidth = 1.5)

plt.show()
