# numpy.polynomial.set_default_printstyle

polynomial.set_default_printstyle(style)

  Set the default format for the string representation of polynomials.

  Values for `style` must be valid inputs to `__format__`, i.e. ‘ascii’ or ‘unicode’.

  Parameters
    style str

      Format string for default printing style. Must be either ‘ascii’ or ‘unicode’.

  Notes

  The default format depends on the platform: ‘unicode’ is used on Unix-based systems and ‘ascii’ on Windows. This determination is based on default font support for the unicode superscript and subscript ranges.

  Examples

      >>> p = np.polynomial.Polynomial([1, 2, 3])
      >>> c = np.polynomial.Chebyshev([1, 2, 3])
      >>> np.polynomial.set_default_printstyle('unicode')
      >>> print(p)
      1.0 + 2.0·x¹ + 3.0·x²
      >>> print(c)
      1.0 + 2.0·T₁(x) + 3.0·T₂(x)
      >>> np.polynomial.set_default_printstyle('ascii')
      >>> print(p)
      1.0 + 2.0 x**1 + 3.0 x**2
      >>> print(c)
      1.0 + 2.0 T_1(x) + 3.0 T_2(x)
      >>> # Formatting supersedes all class/package-level defaults
      >>> print(f"{p:unicode}")
      1.0 + 2.0·x¹ + 3.0·x²
