Here is an excerpt from the PyS60 documentation:

font

The font of the text. There are two possible ways to set this attribute:

*Using a supported Unicode font, for example u"Latin12". Trying to set a font which is not
supported by the device has no effect. A list of supported fonts can be retrieved by using
appuifw.available_fonts.

Example, setting font:
t = appuifw.Text()
t.font = u"albi17b" # sets font to Albi 17 bold
t.font = u"LatinPlain12" # sets font to Latin Plain 12

*Using one of the default device fonts that are associated with the following labels (plain
strings): 'annotation', 'title', 'legend', 'symbol', 'dense', 'normal'

Example,setting font:
t.font = "title" # sets font to the one used in titles
Example, checking the currently set font:
unicodeFont = t.font
The attribute value retrieved is always a Unicode string. If the font has been set with a label, for
example, 'title', the attribute will retrieve the font associated with that label.
