[OfirSiboni]

Hey, added 2 global variables, PRINT_FORMULA and PRINT_LATEX so users can change them and not pass it every time they call the function.

Does your code work if you use

import pytexit
pytexit.PRINT_FORMULA = False

py2tex("...")

?

If so, you should mention such an example in the py2tex() docstring; and maybe in the Notes of the documentation (edit this file ) so that other users can easily use your changes
