It's quite the opposite, actually. Python already has an extremely good and very capable standard library, arguably better than any other language. Python also has a community with a strong sense of what kind of API design best fits with the Python philosophy (which usually boils down to readability and consistency). So there are many efforts going on to improve the standard libraries.

For example, the standard library already has urllib2, which provides HTTP support much better than most other languages' standard libraries. But Requests is a rewrite of it, taking ease of use to a whole new level without compromising any of the features. There is no equivalent in any other language.
