Method on @sym: sympy (x) ¶

The underlying SymPy representation as a string.

Each symbolic sym expression has an underlying Python object, which is stored as a character array consisting of the the object’s srepr (“String Representation”). This method returns that string and can be helpful for debugging or for copy-pasting a sym object into a Python environment such as Jupyter.

Example:

syms x positive
srepr = sympy (x)
  ⇒ srepr = Symbol('x', positive=True)

Unlike @sym/char, the result can be passed directly back to sym with perfect fidelity:

x2 = sym (srepr)
  ⇒ x2 = (sym) x
x2 == x
  ⇒ (sym) True

See also: @sym/char, @sym/disp, @sym/pretty, sym.
