Are there ways to add lines in the axes of a matplotlib figure

I am looking through the documentation of matplotlib for the purpose of adding a tick that separate the axes

http://matplotlib.org/api/axes_api.html

I've already have label that associate with a list of ticks 

axes._setXTicks(ticks, labels, **kwargs)

so I want a thicker line for the additional tick, something like this would be great

axes._setXTicks([0, 5, 7, 10, 15], ["0","5", "thicker tick", "10", "15], **kwargs)

although I want the thicker tick line to be actually a tick that is wider but without labels

Is this possible.

I've tried looking through the document but the closest thing I found is 

axes.axvline(7, *args, **kwargs)

which adds a line through the entire graph in the xth position (7 in this case), although I only wanted a thicker tick

Thanks

You're almost there. Just use the additional arguments ymin and ymax of axvline to set the tick length:

ymin, ymax = axes.get_ylim()
axes.axvline(7, ymin=ymin, ymax=ymin + 0.05*(ymax - ymin))

Note that I calculate the tick length automatically to be 5% of the axes height. This can of course be adjusted. Also, the axvline function takes more arguments to set e.g. the line width.
