比较简单粗暴。数据大了可能不太好

终于做出来一个字符串相关的问题。

def f(n):
lis1 = [i for i in range(65, 91)]
lis2 = []
for i in range(0, n):
if n <= 26:
lis2.append(lis1[i])
else:
lis2 = lis1 + lis1[0:n-26]
lis = lis2 + lis2[-2::-1]
return tuple(lis)
n = int(input('请输入自然数：\n'))
for i in range(1,n+1):
result = f(i)
st = '%c'*(2*i-1) % result
print(st.center(2 * n - 1))

如果n是26的若干倍时，把上面的答案做了点修改。

def f(n):
lis1 = [i for i in range(65, 91)]
lis2 = []
for i in range(0, n):
if int(n / 26) < 1:
lis2.append(lis1[i])
else:
lis2 = lis1 * int(n / 26) + lis1[0:n-26 * int(n / 26)]
lis = lis2 + lis2[-2::-1]
return tuple(lis)
n = int(input('请输入自然数：\n'))
for i in range(1,n+1):
result = f(i)
st = '%c'*(2*i-1) % result
print(st.center(2 * n - 1))
