Hi I'm new to Python and I would like to know how he deals with memory space. I thought I had understood but I made a test and the results were uncoherenent with my understanding, here is the thing:
>>> a=[1,2] >>> l=[a,a] >>> id(a); id(l[0]); id(l[1]); 61659528 61659528 61659528 >>> #All Have the same ID >>> l[0]=[0,0] >>> l [[0, 0], [1, 2]] >>> #Why didn't l[1] change as well? >>> id(a); id(l[0]); id(l[1]); 61659528 61390280 61659528 >>> #How come id(l[0]) changed? >>> a = [4,4] >>> l [[0, 0], [1, 2]] >>> #Why didn't l[1] change? l[1] and a were occupying the same memory adress! Thank you for answering :)
