python怎么打印菱形

rows = int(input('请输入菱形边长：\n'))

row = 1

while row <= rows:

    col = 1     # 保证每次内循环col都从1开始，打印前面空格的个数

    while col <= (rows-row):  # 这个内层while就是单纯打印空格

        print(' ', end='')  # 空格的打印不换行

        col += 1

    print(row * '* ')  # 每一行打印完空格后，接着在同一行打印星星，星星个数与行数相等，且打印完星星后print默认换行

    row += 1

bottom = rows-1

while bottom > 0:

    col = 1     # 保证每次内循环col都从1开始，打印前面空格的个数

    while bottom+col <= rows:

        print(' ', end='')  # 空格的打印不换行

        col += 1

    print(bottom * '* ')  # 每一行打印完空格后，接着在同一行打印星星，星星个数与行数相等，且打印完星星后print默认换行

    bottom -= 1

请输入菱形边长：
