[SciPy-user] possibly stupid question

[Charles Hebert]

Try :

 >>> import numpy
 >>> a = numpy.arange(100)
 >>> b = a[:14]
 >>> b
array([ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13])
 >>> c = a[15:]
 >>> c
array([15, 16, 17, ....
83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99]

C.
