a=[[0]*5]*4
pass #breakpoint
a[2][2]=1
pass #breakpoint
` print(a)
when i run this scripts it returned :
` [[0, 0, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 1, 0, 0]]
but i wish it returned out like this:
` [[0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 1, 0, 0], [0, 0, 0, 0, 0]]
so why? I know how to use ‘for’ command to create an list that could fix this problem.but sorry i am new to python and i just study it to pass a exam. pwp
I don’t want to get so caught up in this simple question that it consumes too much time.awa
so is this a bug? sorry my english is so poor.
