Good for user defined classes where it is inconvenient to patch the Printers, which works great for built-in SymPy objects, but not that Therefore all printing code was combined into the different Is hard to produce a high quality printer, if all the methods are spread Its own latex, mathml, str and repr methods, but it turned out that it This was the original way of doing printing in sympy. The name of the method is specified there. Look at the documentation of the printer that you want to use. The name of that methodĭepends on the specific printer and is defined under Printer.printmethod.įor example, StrPrinter calls _sympystr and LatexPrinter calls _latex. The printer looks for a specific method in every object. While looking for the method, it follows these steps: Print the given expression in the given style that the printer defines. This method looks for an appropriate method which can The whole printing process is started by calling. Which Method is Responsible for Printing? # Take the best fitting method defined in the printer.Īs fall-back use the emptyPrinter method for the printer. Let the object print itself if it knows how. Passed to a designated Printer who then is responsible to return anĪdequate representation of that expression.
