What does 'inf' mean?

I keep noticing this but I don’t know what its for.

You may need to be more specific. Where have you seen inf?


Line 7

It’s a constant similar to pi.
I found this definition:

math. inf

A floating-point positive infinity. (For negative infinity, use -math.inf .) Equivalent to the output of float('inf') .

New in version 3.5.
