Infinity in Python (float('inf'), math.inf) | FavTutor
July 21, 2026 - No. Infinity exists only as a float; int("inf") raises a ValueError and int(float("inf")) raises an OverflowError. Python ints are unbounded, so no integer infinity is needed, and float infinity still compares correctly against any int.

May 4, 2023 - We can use the float() function in Python to represent the positive infinity and negative infinity. For positive infinity, we need to pass 'inf' to the float() function and for negative infinity, we need to pass '-inf' to the float() function.

December 11, 2023 - You could accomplish this by annotating retries: int | float and passing retries=float("inf") or retries=math.inf, but it would be nice if you could just pass int("inf") and not need to change the type annotation.

In Python, you can do:
test = float("inf")
In Python 3.5, you can do:
import math
test = math.inf
And then:
test > 1
test > 10000
test > x
Will always be true. Unless of course, as pointed out, x is also infinity or "nan" ("not a number").
Additionally (Python 2.x ONLY), in a comparison to Ellipsis, float(inf) is lesser, e.g:
float('inf') < Ellipsis
would return true.

Since Python 3.5 you can use math.inf:
>>> import math
>>> math.inf
