indexed assignment in list

saw this snippet on the internet : why assigning by index propagates it all? >>> a = [[1]] * 7 >>> a [[1], [1], [1], [1], [1], [1], [1]] >>> a[0][0] = 2 >>> a [[2], [2], [2], [2], [2], [2], [2]] why not [[1], [2], [2], [2], [2], [2], [2]] ? thank you ! -- Abdur-Rahmaan Janhangeer https://git
