Python利用Prim算法生成迷宫
作者：Leleprogrammer
Prim算法随机生成后的迷宫数列矩阵如下图：

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
实现该效果的代码如下：
import random as rd
nearmaybe=[
[-2,0],
[2,0],
[0,-2],
[0,2]
]
def createMaze(row,col):
maze=[[0 for i in range(col)] for i in range(row)]
check=[]
firstrow=rd.randrange(1,row-2,2)
firstcol=rd.randrange(1,col-2,2)
maze[firstrow][firstcol]=1
check.append([firstrow,firstcol])
while len(check):
c=rd.choice(check)
nears=[]
conditions=[]
for maybe in nearmaybe:
conditions.append([c[0]+maybe[0],c[1]+maybe[1]])
for condition in conditions:
if condition[0]>=1 and condition[0]<=row-2 \
and condition[1]>=1 and condition[1]<=col-2:
nears.append([condition[0],condition[1]])
for n in nears.copy():
if maze[n[0]][n[1]]:
nears.remove(n)
for block in nears:
if block[0]==c[0]:
if block[1]<c[1]:
maze[block[0]][c[1]-1]=1
maze[block[0]][block[1]]=1
check.append([block[0],block[1]])
else:
maze[block[0]][block[1]-1]=1
maze[block[0]][block[1]]=1
check.append([block[0],block[1]])
else:
if block[0]<c[0]:
maze[c[0]-1][block[1]]=1
maze[block[0]][block[1]]=1
check.append([block[0],block[1]])
else:
maze[block[0]-1][block[1]]=1
maze[block[0]][block[1]]=1
check.append([block[0],block[1]])
if not len(nears):
check.remove(c)
maze[1][1]="s"
while True:
c=rd.randint(1,col-2)
if maze[row-2][c]:
maze[row-2][c]="e"
break
return maze调用该函数的方法：
maze=createMaze(27,27)
for l in maze:
for s in l:
print(s,end=" ")
print()
CreateMaze传入的两个参数必须都是单数，否则程序可能会无法运行！
下面的for循环遍历就是将生成的迷宫矩阵打印出来
S表示出发点
1表示路
0表示墙
E表示终点
生成迷宫矩阵后，就可以将其引用到游戏中去啦！
