Hello, Why ipython and python interactive shell give two different information?
--- ipython Python 2.4.4 (#2, Oct 20 2006, 00:23:25) Type "copyright", "credits" or "license" for more information. IPython 0.7.2 -- An enhanced Interactive Python. ? -> Introduction to IPython's features. %magic -> Information about IPython's 'magic' % functions. help -> Python's own help system. object? -> Details about 'object'. ?object also works, ?? prints more. In [1]: from scipy import linalg In [2]: help(linalg.eig) Help on function eig in module numpy.linalg.linalg: eig(a) eig(a) returns u,v where u is the eigenvalues and v is a matrix of eigenvectors with vector v[:,i] corresponds to eigenvalue u[i].
