Dans toutes les versions de Python, nous pouvons représenter l'infini et NaN ("pas un nombre") comme suit: pos_inf = float('inf') # positive infinity neg_inf = float('-inf') # negative infinity not_a_num = float('nan') # NaN ("not a number") So, let us now know about all the methods we can represent positive and negative infinity. Integers are inherently finite. En Python 3.5, vous pouvez faire: import math test = math.inf. not_a_number: .NAN infinity: .inf negative_infinity: -.inf. But we can use float (inf) as an integer. 1.
