Axes Props

You can control the axis tick and grid properties

import matplotlib.pyplot as plt
import numpy as np

t = np.arange(0.0, 2.0, 0.01)
s = np.sin(2 * np.pi * t)
fig, ax = plt.subplots()
ax.plot(t, s)
ax.grid(True)

ticklines = ax.get_xticklines() + ax.get_yticklines()
gridlines = ax.get_xgridlines() + ax.get_ygridlines()
ticklabels = ax.get_xticklabels() + ax.get_yticklabels()

for line in ticklines:
    line.set_linewidth(3)

for line in gridlines:
    line.set_linestyle('-.')

for label in ticklabels:
    label.set_color('r')
    label.set_fontsize('medium')

plt.show()
