class sbmlmath.mathml_printer.SBMLMathMLPrinter(*args, literals_dimensionless=True, sbml_level=3, sbml_version=2, **kwargs)[source]

Bases: MathMLContentPrinter

MathML code printer.

This printer converts SymPy expressions to MathML code that can be used in SBML models.

Note:

  • assumes all constants are dimensionless

Parameters:

  • sbml_level (int)

  • sbml_version (int)

doprint(expr, with_prolog=True, with_math=True)[source]

Convert SymPy expression to MathML string.

Parameters:

  • expr – The SymPy expression to be converted.

  • with_prolog – Whether to include the XML prolog.

  • with_math – Whether to include the <math> tags.
