The syntax as it is already defined in the PEP can be used to define what we need. The part that was unclear was about the meaning of "2.5". e.g.: 2.5.0 or 2.5.x.. It became obvious in the thread that it means 2.5.x. (e.g. a range) so there's no need to introduce any range operator, wether it's "~=" or a new notation with ":". IOW, since the syntax already present in the PEP is sufficient for our needs (besides ~=) , and as long as the precise definition of "version string" is provided, I consider that further discussion about the syntax itself is more or less bikeshedding. I am now rewriting the relevant section of the PEP with the examples we discussed in this thread, but the operators should stay the same as they were initially: "<", ">", "<=", ">=", "==" and "!=".
