Question

假设我有四个多维数组 -

a = [["a","a","a"],
    ["a","a","a"],
    ["a","a","a"]]
b = [["b","b","b"],
    ["b","b","b"],
    ["b","b","b"]]
c = [["c","c","c"],
    ["c","c","c"],
    ["c","c","c"]]
d = [["d","d","d"],
    ["d","d","d"],
    ["d","d","d"]]

我想把它们组合成一个数组，比如

total = [["a","a","a","b","b","b"],
        ["a","a","a","b","b","b"],
        ["a","a","a","b","b","b"], 
        ["c","c","c","d","d","d"],
        ["c","c","c","d","d","d"],
        ["c","c","c","d","d","d"]]

我该怎么做？

我这样做是为了洞穴式 map 生成

Answer 1

可能是这样的:

top = list(x+y for x,y in zip(a,b))
bottom = list(x+y for x,y in zip(c,d))
total = top + bottom

for r in total: print(r)

输出:

['a', 'a', 'a', 'b', 'b', 'b']
['a', 'a', 'a', 'b', 'b', 'b']
['a', 'a', 'a', 'b', 'b', 'b']
['c', 'c', 'c', 'd', 'd', 'd']
['c', 'c', 'c', 'd', 'd', 'd']
['c', 'c', 'c', 'd', 'd', 'd']
