The link below leads to a recent related thread on this list. Maybe it will be informative. I believe it implies that the answer is No, you have to use TeX.

How can I save a matplotlib figure with text as a postscript image and that
the text will be saved as text. Currently when I save the image as
postscript all the text in the image ( xlabel, ylabel etc.. ) is saved as
path and not as text.. Is it possible to save it as text?
If I use the following code ( use latex)
matplotlib.rcParams["text.usetex"] = True
and save the image as postscript the text is saved as text.. But I do not
want to use latex.. Is it possible without latex?
