[IPython-dev] Integrating pandas into pylab

I think EPD distributed a magic called %whoosh which let you do full 
text searching in docstrings which is roughly the equivalent to 
lookfor. I'll try to add it to Spyder during the next year and you can 
read about it here:

http://pypi.python.org/pypi/WhooshDoc/1.0

About the flat namespace, it's a great idea, specially to use it with 
the new ipython notebook (maybe as a profile, at least at the 
beginning). I think it would be better if it could be accompanied by a 
comprehensive Py4Science book which described what you can get from it. 
Something similar to the Mathematica book, with topics like these:

1. Core Language
A Python intro from the scientific point of view

2. Data structures:
Vectors/Matrices = Numpy arrays
Tabular Data = DataFrame

3. Linear algebra
dot, cross, norm, etc

4, Symbolic Mathematics
Variables = Sympy symbols
Integration/derivation/ODEs

5. Probability
Distributions = Scipy.stats
Random numbers = numpy.random

6. Graphics
2D = mpl.plot
3D = mayavi.mlab
3D interactive = VPython

7. Interfaces
IPython

lookfor and a book like this one will be a great improvement for any 
newbie trying to get started with python.

Cheers and keep up the good flow of ideas,
Carlos
