First of all, thanks for your suggestion, and for taking the time to help improve Python. As noted, random.uniform probably does what you want, so we don't really need this function. But in case it's of interest to you, there's some additional considerations around proposed additions to the stdlib that we'd normally look at with a suggestion like this. If you find any other improvements you'd be interested in proposing, it might be helpful to you to be aware of them. The first thing that struck me was the performance of your approach. With multiple number<->string conversions it is likely to be extremely slow, making this function completely unsuitable for things like simulations, where the ability to generate many millions of results fast is critical. Python stdlib functions typically get used in a wide range of situations, and we need to make sure they are suitable for as large a range of applications as we can. Also, I'd be curious to know how you tested your function. Random number generators are notoriously difficult to get right, and you are here combining the results of multiple calls to the underlying PRNG. By doing so, you might (as far as I know, it's unlikely, but it's possible) have degraded the randomness of the result. Did your function pass the standard tests for randomness? Note: I don't know what those tests are, but I do know that such things exist, and I'd expect anything in the stdlib to have been validated by people who *do* know such things. Again, stdlib functions get used in a wide range of applications, and the authors typically rely on the Python developers to have "got the details right" on their behalf. Anyway, these are just a couple of thoughts for you. I hope they were of interest, and thanks again for contributing. Paul
