No. "import numpy" is essentially the same as the pure Python equivalent; it loads the module and puts it into the namespace. cnp.import_array() loads the module (or reuses the already loaded one), does not put it into any namespace, but then, most importantly, grabs the pointer to the table of function pointers and assigns it to the local void** variable. All of the numpy API is made available to third-party extension modules by #define macros which look up into this table. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
