Hello! I wrote next code. I intended to insert class object to Pool list.
<Code>========================================== import random,copy class Particle: Dimension = 2 CurrentPosition = {} def __init__(self, dimension): self.Dimension = dimension for i in range(self.Dimension): value = random.uniform(0.,1.) self.CurrentPosition[i] = value class Group: Pool = [] def __init__(self, size, dimension): for i in range(size): particle = Particle(dimension) print 'particle generated' print particle.CurrentPosition self.Pool.append(copy.deepcopy(particle)) print '\n total Pool' group = Group(3, 2) for i in group.Pool: print i.CurrentPosition ============================================== But the result is like follow. It always synchronized with final insertion. What do you think is the problem ? <Results>======================================= $ python test3.py particle generated {0: 0.70968382903877392, 1: 0.8019162560229226} particle generated {0: 0.76791838585848948, 1: 0.91689882120031052} particle generated {0: 0.32582853916678456, 1: 0.72166384931732286} total Pool {0: 0.32582853916678456, 1: 0.72166384931732286} {0: 0.32582853916678456, 1: 0.72166384931732286} {0: 0.32582853916678456, 1: 0.72166384931732286} ============================================== Thank you in advance !
