Unlikely that it was you - some email packages/web-page presentations
have a mind of their own!

If the result can be computed as a string (or graphic) for printing, it
can be a Python object (variable).

Which brings me to ask (apologies for nosiness): using
sub-/super-scripts and fractions, which must fit within the current
line-height, must surely be more difficult to read - so why do it (that
way)?


Extending further, a suggestion to look at Tex/Latex (which was
apparently only sent to me, cf entire list) looked likely. One reason
that package was invented (by a ComSc 'luminary' no-less!) was to enable
the printing of math formulae/formulas in traditional text-book and math
notation instead of the numerator/denominator format forced upon us by
typewriters.

However, is it possible to combine wxPython with Tex?



NB to continue to read beyond this point illustrates why top-posting is
'frowned upon' by the list, ie the logic of a question-then-answer
sequence in this type of forum
