下邊的程式碼是6階蛇形矩陣的構造和輸出

N = 6
counter=[]
for a in range(N):
    counter.append(N-a)
    counter.append(N-a)
del counter[0]
counter[0]=counter[0]-1
counter.append(1) #把N階蛇形每次要走的步數計算出來存到一個LIST裡，每個方向的最後一個賦值屬於下一個方向的第一步
print(counter)
value = 1
rowID=0
colID=0
multilist = [[0 for col in range(N)] for row in range
 
(N)]
print(multilist)
for i in range(len(counter)):
    for j in range(counter[i]):
        if(i % 4 == 0):
            multilist[rowID][colID] = value
            if(colID != N - 1):
                colID += 1
if (i % 4 == 1):
            multilist[rowID][colID] = value
            if (rowID != N - 1
 
):
                rowID += 1
if (i % 4 == 2):
            multilist[rowID][colID] = value
            if (colID != 0):
                colID -= 1
if (i % 4 == 3):
            multilist[rowID][colID] = value
            if (rowID != 0):
                rowID -= 1
value += 1
for e in multilist:
    print
 
(e)
for e in multilist:
    for e2 in e:
        print(e2),

最終執行結果如下圖
