numpy slice: create view, not copy

2006-10-12 Thread K. Jansma
Hi, given an array: import numpy a = numpy.arange(100).reshape((10,10)) print a [[ 0 1 2 3 4 5 6 7 8 9] [10 11 12 13 14 15 16 17 18 19] [20 21 22 23 24 25 26 27 28 29] [30 31 32 33 34 35 36 37 38 39] [40 41 42 43 44 45 46 47 48 49] [50 51 52 53 54 55 56 57 58 59] [60 61 62 63 64 6

share function argument between subsequent calls but not between class instances!

Hi, given the following example class class Test: def f(self,a, L=[]): L.append(a) return L and the following statements a = Test() a.f(0) a.f(0) a.f(0) b = Test() b.f(0) this is the output I would like to have (i.e., expect) >>> a = Test() >>> a.f(0) [0] >>> a.f(0) [0, 0]
