Yesterday uses List to construct a 2-dimensional number of M * N
Starting to write this
Self.cells = [[0] * n] * m
Subsequently assign each element, find that each line is the same
Deductively awake the List of each row pointing to the same element
a [0] IS A [1]
Return true
Such
Change the writing method
Tempcell = [0] * col
For i in inregation:
Self.cells.Append (Tempcell [:]) #copy! Not Reference
Copy content from Tempcell [:] produces a new list,
Instead of passing the reference, remember to remember!
