All the modules/libraries available for Python really make it powerful. Code reuse is a wonderful thing when you can do it, but you have to write with that in mind.
One other issue with using the * operator on import is there is a danger of losing track of which functions you are actually using. If you use short aliases then it is not big deal to make the module obvious.
I am writing Python most days for work and I enjoy it more than many other languages I have used.
