python - Python 打印矩阵

问题描述

你能帮助我如何以正确的方式打印这个吗？我尝试了很多方法，但都没有奏效

while True:
    m = int(input())
    mlen = m
    sm = 1
    aux = 1
    matriz = []

    if m == 0:
        print()
        break

    for i in range(m):
        linha = []
        for j in range(m):
            linha.append(sm)
        matriz.append(linha)

    while m - 2 > 0:
        for i in range(aux, m - 1):
            for j in range(aux, m - 1):
                matriz[i][j] = sm + 1
        sm += 1
        aux += 1
        m -= 1
    for i in matriz:
        for j in i:
            print('{:4}'.format(j), end='')
        print('')

我必须像下面的例子一样打印矩阵。这是一个 URI Online Judge 练习（编号 1435）。下面的点是空格，在矩阵的最后一个元素之后我不能有任何空格。

解决方案

尝试使用str.rjust(width[, fillchar])，然后您可以使用fillchar来获取点
