# Polynomials with coefficients in Zp - python SyntaxError

Hi,

I am trying to create ℤₚ[x], the set of polynomials with coefficients in ℤₚ, with the following syntax :

Zp = Integers(p)

PRZp.<x> = Zp[]

This works fine in the sage interpreter, but in a python file I get a syntax error at the "<" character. How can I solve this ? I've tried alternatives, like PRZp = PolynomialRing(Zp, 'x'), but this fails too with a "NameError: name 'x' is not defined" when I define a polynomial expression after that.
