numpy.polynomial.set_default_printstyle#
- polynomial.set_default_printstyle(style)[source]#
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:
- stylestr
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·x + 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 + 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·x + 3.0·x²
