python - 在 python 上的矩阵一侧创建条形

Question

我想制作一个矩阵nxn，但在垂直边我想放“|”但我无法使用下面的代码来做到这一点:

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

更改您的 printMatriz 函数以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("|")
