Python 实现打印单词的菱形字符图案

a = [1, 2, 3, 4, 5, 6, 7, 6, 5, 4, 3, 2, 1]
b = [' ' * 2 * (7 - i) + 'Good' * i for i in a]
for line in b:
 print(line)

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

s = '*'
for i in range(1, 8, 2):
 print((s * i).center(7))
for i in reversed(range(1, 6, 2)):
 print((s * i).center(7))
