用python打印菱形的实操方法和代码

rows = int(input('请输入菱形边长：/n'))row = 1while 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-1while 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
