`numpy.polynomial._polybase:ABCPolyBase.degree`

Signature

def degree ( self )

The degree of the series.

degree : int: Degree of the series, one less than the number of coefficients.

Create a polynomial object for ``1 + 7*x + 4*x**2``:

np.polynomial.set_default_printstyle("unicode")
poly = np.polynomial.Polynomial([1, 7, 4])
print(poly)
poly.degree()

Note that this method does not check for non-zero coefficients. You must trim the polynomial to remove any trailing zeroes:

poly = np.polynomial.Polynomial([1, 7, 0])
print(poly)
poly.degree()
poly.trim().degree()
