numpy.polynomial.set_default_printstyle — NumPy v2.4.dev0 Manual (original) (raw)

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
