To learn more, see our tips on writing great answers. SymPy expressions are built up from symbols, numbers, and SymPy functions, In [2]: x, y, z = symbols('x y z') SymPy automatically pretty prints symbols with greek letters and subscripts. For example, I'm suggesting you can just use them: "I was wondering if there is a way to directly enter it into my console" sure the same way you directly enter.
