怎么在行列长度固定的情况下循环输出字典

假设行列长度都为5，但字典长度及值为4。当值的长度小于假设值时，就重复值，当字典的长度小于假设值时，也是重复字典，直到满足条件为止。如下图所示

就不断叠加行和列，然后取一定限制，献上代码：

def print_pattern(pattern, limit):
    rows = []
    for r in range(len(pattern)):
        col = pattern[r]
        while len(col) < limit:
            col += pattern[r]
        else:
            col = col[:limit]
        rows.append(col)
    while len(rows) < limit:
        rows += rows
    else:
        rows = rows[:limit]
    print('\n'.join(rows))


patterns = {0: '0123', 1: '1230', 2: '2301', 3: '3012'}
print_pattern(patterns, 5)
print()
patterns = {0: '@#$', 1: '#$@', 2: '$@#'}
print_pattern(patterns, 5)
