Define an Infinite Number in Python

You can define an infinite number in Python as follows,

infinite_number = float('inf')

Let's print it out.

print(infinite_number)

Output:

inf

Example:

>>> infinite_number = float('inf')
>>> print("Positive Infinite Number:",infinite_number)
Positive Infinite Number: inf
>>> 
>>> if(1000 < infinite_number):
...   print(f"{infinite_number} is greater than 1000")
... 
inf is greater than 1000
>>> negative_infinite_number = float('-inf')
>>> print("Negative Infinite Number:",infinite_number)
Negative Infinite Number: inf
>>> 
>>> if(1000 > negative_infinite_number):
...   print(f"1000 is greater than {negative_infinite_number}")
... 
1000 is greater than -inf
>>>
