Well, actually, this brings up a concern I have.
Suppose I want to use the class scipy.interpolate.interp1d, but I
don't know how.
In : scipy.interpolate.interp1d?
Base Class: <type 'type'>
String Form: <class 'scipy.interpolate.interpolate.interp1d'>
Interpolate a 1D function.
splrep, splev - spline interpolation based on FITPACK
UnivariateSpline - a more recent wrapper of the FITPACK routines
Uh, great, but how do I actually *use* it?
In : scipy.interpolate.interp1d.__init__?
String Form: <unbound method interp1d.__init__>
Definition: scipy.interpolate.interp1d.__init__(self, x, y,
kind='linear', axis=-1, copy=True, bounds_error=True, fill_value=nan)
Initialize a 1D linear interpolation class.
x and y are arrays of values used to approximate some function f:
y = f(x)
This class returns a function whose call method uses linear
interpolation to find the value of new points.
x : array
How are users supposed to find .__init__? This is what they need to
use to actually create an instance of the class, but the information
is not presented when they look at the class' docstring. Even a
moderately experienced user might have no idea there was a method
called __init__ whose docstring would have alleviated their suffering.
Should the class' docstring suggest users look at the docstring of
.__init__? Should it *include* that docstring? There must be a general
python solution to this...
