pylab interface• Plotting should just work
• Easy plots should be easy
• GUI / interactive complexity should be managed
• ipython to the rescue
IPython 0.6.12_cvs -- 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.
Welcome to pylab, a matplotlib-based Python environment help(matplotlib) -> generic matplotlib information help(pylab) -> matlab-compatible commands from matplotlib help(plotting) -> plotting commands
In [1]: plot([1,2,3])

Fits your brain: “hello world” in 4 languages
MLOSS: Whistler 2008
scalable, versatile scales from interactive scripts to full blown apps doesn't force one programming paradigm on
you plays very well with other languages

Fits your brain (part II):
But I think this is the
python

interactive interlude
the interactive shell, rich data structures, numpy arrays, pylab mode
rich text support, what you see is what you get, mathtext
