在python上的matriz一侧创建条

Question

我想做一个matriz nxn，但在垂直面上我想放“|”，但我不能用下面的代码：

def creatematriz(nlines, ncoluns, valor):
    M = []
    for i in range(nlines):
        line = []
        for j in range(ncoluns):
            line.append(valor)
        M.append(line)
    return M
def printMatriz(matriz):
    for line in matriz:
        for position in line:
            print(position, end=" ")
        print("|")
def main():
    m=creatematriz(20,6,'0')
    printMatriz(m)
main()

我想要这样的东西：

| 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 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 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 0 0 0 0 0 0 0 0 0 |

但我只得到：

 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 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 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 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0|

Answer 1

将printMatriz函数更改为在内部循环之前打印|：

def printMatriz(matriz):
    for line in matriz:
        print("|", end="")
        for position in line:
            print(position, end=" ")
        print("|")

Answer 2

也可以只使用一个循环和join函数：

def printMatriz(matriz):
    for line in matriz:
        print("| " + " ".join(line) + " | ")
