Changing the properties of the individual grid line can be tricky.
The easier way in my opinion is to draw another line with thinker linewidth.
ax=subplot(111)
ax.grid()
from matplotlib.transforms import blended_transform_factory
# for x=0
trans = blended_transform_factory(ax.transData, ax.transAxes)
ax.plot([0,0], [0,1], "-",
transform=trans,
color="red", linewidth=2,
zorder=5)
# for y=0
trans = blended_transform_factory(ax.transAxes, ax.transData)
ax.plot([0,1], [0,0], "-",
transform=trans,
color="blue", linewidth=2,
zorder=5)
