python - Python 数组（获取正确的语法顺序）

Question

如果您运行此代码，则两个输出是相同的：['A','B',' ',' ']. 不知道我做错了什么，但输出不应该array2是空白：[' ',' ',' ',' ']并且array1应该是：['A','B',' ',' ']？

reset = [" "," "," "," "]

array1 = []
array2 = []

array1.append([" "," "," "," "])
array2 = array1

array1[0][0] = "A"
array1[0][1] = "B"

print (array1)
print (array2)
