[Numpy-discussion] Indexing

Hi,

 

I stumbled across this anomaly, the assignment to ncycle[i][b] fails,
yet ncycle[:][b] works and the final print works.  Is this a known bug
or limitation ?  I am running numpy-1.2.1 with python 2.5.4

 

Gerry

 

from numpy import *

 

ncycle = arange(10)

i = array([0, 1,  2,  3,  4,  5,  6, 7])

b = array([True,False]*2)

 

ncycle[i][b] = 99

print ncycle

 

ncycle[:][b] = 99

print ncycle

 

print ncycle[i][b]
