4 min readTo add a generator to a SymPy Poly object, you can use the add_gen method. This method takes a string or symbol as an argument and adds it as a new generator to the polynomial. For example, you can create a new Poly object with a generator 'x' and then add another generator 'y' to it using the add_gen method. This allows you to work with polynomials in multiple variables and perform operations such as addition, multiplication, division, etc. using the newly added generator.
