How to change float('inf') representation?-CodePudding

I want to change float('inf') representation -> ∞, can u help me with it? I try to use this, but it didn't work

class Inf(float('inf')):
    def __repr__(self) -> str:
        return '∞'

inf=Inf()

those, when I use print() I want to see '∞' instead 'inf'

I want result like in

from sympy import oo

but get it with oop

CodePudding user response：

drop the ('inf') in class inheritance. You inherit from classes, not their instances. Then in __repr__ check if your float is infinity.

class FloatWithGlyphInf(float):
    def __repr__(self) -> str:
        if self == float('inf'):
            return '∞'
        else:
            return super().__repr__()

print(FloatWithGlyphInf('inf')) # ∞
print(FloatWithGlyphInf('0'))   # 0.0
