Hi folks,
I've added this little bit of code to the default ipython -pylab startup:
exec ("import numpy\n"
"import numpy as np\n"
"import matplotlib\n"
"import matplotlib.pylab as pylab\n"
"try:\n"
" import matplotlib.pyplot as plt\n"
"except ImportError:\n"
" pass\n"
) in user_ns
to try and encourage use of the 'canonical' ways of calling/executing
numpy and mpl calls. This is just in my branch, not publicly visible
yet. I wanted to know:
1. If I should keep the try/except around.
2. If this is your 'approved' manner of loading. It worries me a bit
that if we promote pyplot/plt as the entry point, it needs a proper
docstring. Just try 'pylab?' vs 'pyplot?' and you'll see the
difference.
Cheers,
f
I've added this little bit of code to the default ipython -pylab startup:
The latest releases of pylab already provide np and plt in the pylab namespace.
Would it be better to simply add a "pyplot" mode to ipython to
encourage the proper usage, and in this mode import only as few
symbols (np, plt, and sp if possible)?

We can easily add the docstring for the next bug fix release

Besides, for ipython the 'import *' mode *is* a reasonable use case,
since when you're working interactively, you really just want to type
plot(x,cos(x**2)+sin(x**3))
and not some plt.foo/np.bar contraption. So I think there remains a
use case for importing all the names in at the top level (remember
that you can configure now ipython to NOT do 'from pylab import *'
anymore if you reall want a clean namespace).
The use case is mostly to provide an environment where the standard
examples and docstrings that may use either numpy or np,
pylab/pyplot/plt are always defined, so users can copy/paste without
fear.
Cheers,
