Represent infinity as an integer in Python 2.7

Question

I am wondering how to define inf and -inf as an int in Python 2.7. I tried and it seems inf and -inf only works as a float.

a = float('-inf') # works

b = float('inf') # works 

c = int('-inf') # compile error, ValueError: invalid literal for int() with base 10: 'inf' 

d = int('inf') # compile error, ValueError: invalid literal for int() with base 10: 'inf'

Answer 1

In, Python there is no way to represent infinity as an integer in Python. This matches the behaviour of many other languages. However, due to Python's dynamic typing system, you can use float('inf') in place of an integer, and it will behave as you would expect.
