IPython 0.8.1 -- 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]: a = 'foo' In [2]: b = 'bar' In [3]: c = 5.234 In [4]: import os In [5]: d = os In [6]: whos Variable Type Data/Info ------------------------------ a str foo b str bar c float 5.234 d module <module 'os' from '/usr/lib/python2.5/os.pyc'> os module <module 'os' from '/usr/lib/python2.5/os.pyc'> In [7]: import numpy as np In [8]: aa = np.zeros(100) In [9]: whos Variable Type Data/Info ------------------------------- a str foo aa ndarray 100: 100 elems, type `float64`, 800 bytes b str bar c float 5.234 d module <module 'os' from '/usr/lib/python2.5/os.pyc'> np module <module 'numpy' from '/us<...>ages/numpy/__init__.pyc'> os module <module 'os' from '/usr/lib/python2.5/os.pyc'> And I trust you've heard of numpy, scipy and matplotlib? http://www.scipy.org/ http://matplotlib.sourceforge.net/ http://numpy.scipy.org/ Cheers, Kurt
