WebbYou must create a list of size n × m, filled with, say, zeros. The obvious solution appears to be wrong: a = [ [0] * m] * n This can be easily seen if you set the value of a [0] [0] to 5, and then print the value of a [1] [0] — it will also be equal to 5. The reason is, [0] * m returns just a reference to a list of m zeros, but not a list.
