Python nested loop speed issues -

-

i working on program test ideal angle-values construct something. i'm stuck @ nested-for-loop i'm going attach below. while idealy count each 'a' 9000, takes forever if values set below. there way speed nested loop? or can somehow assign more ressources python?

for a1 in  xrange(15, 91):     a2 in xrange(15, 91):         a3 in xrange(15, 91):             a4 in xrange(15, 91):                 a5 in xrange(15, 91):                     ite in xrange(1, 1000):                         ok = mathmatvec(a1, a2, a3, a4, a5, ite)                          if ok == 1:                                 v[0] = a1                                 v[1] = a2                                 .                                 .

the itertools.product() function speed nested for-loops.

that said, running time dominated total number of calls mathmatvec().

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @...
