arrays - Python Memorry error -

i new python , below code,

import numpy np val = 4**10 q = [] j in range(60): = [] in range(val): tmp = (i+j)**2 a.append(tmp) q.append(a) t= zip(*q) g = [] t in t: tmps2 = np.average(t) g.append(tmps2)

below code error:

memoryerror traceback (most recent phone call last) c:\python27\lib\site-packages\ipython\utils\py3compat.pyc in execfile(fname, glo b, loc) 169 else: 170 filename = fname --> 171 exec compile(scripttext, filename, 'exec') in glob, loc 172 else: 173 def execfile(fname, *where): c:\users\user\desktop\simpl.py in <module>() 13 14 ---> 15 t= zip(*q) 16 17 g = [] memoryerror:

so, can expert explain me, computer still have 1.5gb memory.

you can accomplish much more efficiently with:

i,j= np.indices((60, 4**10)) q = (i+j)**2 g = np.average(q, axis=0)

the biggest advantages are:

avoid loops more efficient memory usage.

in illustration transpose of q not used, not memory error.
