Is there anything like +infinity and -infinity available in Python, and
can it be used in comparisons together with int or float numbers?
To lazy to look it up, so let's try:

Looking it up might be good, though... See, for example, PEP 754,
"IEEE 754 Floating Point Special Values":
http://www.python.org/peps/pep-0754.html
The problem is that the expression float('infinity') works on some
platforms, along with float('Inf'), but, as the PEP points out, on
many systems you'll just get an error. You could also try stuff like
float(1e3000).
So, my response to the original question would be "sort of" -- since
it's there, but it's not particularly reliable. Let's just hope that
PEP 754 (or something similar) is accepted; infinity _is_ certainly
useful...
