Relationship between SciPy and NumPy
...
Last time I checked it, the scipy __init__ method executes a
from numpy import *
so that the whole numpy namespace is included into scipy when the scipy module is imported.
The log10 behavior you are describing is interesting, because both versions are co...

returns a list of tuples. This is fine when foo and bar are not massive. If they are both massive then forming zip(foo,bar) is an unnecessarily massive
temporary variable, and should be r...
