It sounds like all of this could be done very simply without going to
C, using a class based on numpy.ndarray. The following works for 1D
arrays, behaves like a regular 1D numpy array, and could be easily
improved with a little care. Is this what you had in mind?
import numpy
#easy scalable array class
class scarray:
def __init__(self,*args,**kwargs):
self.__data = numpy.ndarray(*args,**kwargs)
def append(self,val):
tmp = self.__data
self.__data = numpy.ndarray(tmp.size+1)
self.__data[:-1] = tmp
self.__data[-1] = val
del tmp
def __getattr__(self,attr):
return getattr(self.__data,attr)
x = scarray(5)
x[:] = numpy.arange(5)
print x
x.append(5)
print x
