How to modify the text in a bar chart

I have created a bar chart, with some text inside each bar, now, I would like to knkow if it is possible to modify the size of this text, the font size, in order to reduce it a bit.

I have generated it like this:

    #some stuff
    ...
    ...
    rects1 = plt.bar(test, y, bar_width, alpha=opacity, color='b')
    labels = []
    for bar in rects1:
        height = bar.get_height()
        ax.text(bar.get_x()+bar.get_width()/4., 0.65*height, '%.2f'%float(height), rotation='vertical', horizontalalignment='left', va='bottom')
        labels.append(bar.get_x()+bar.get_width()/2.)
    ...
    ...
    ...

And the result looks more or less like this:

You are probably looking for this: http://matplotlib.org/users/text_props.html

For instance you can add

ax.text(bar.get_x()+bar.get_width()/4., 0.65*height, '%.2f'%float(height), rotation='vertical', horizontalalignment='left', va='bottom', weight='bold')

To use a bold font. You can use fontsize=somenumber to change the font size.
