求三角形
n = int(input())
count1 = (1 + n) * n // 2
count2 = n * n
lis1 = [str(i).zfill(2) for i in range(1,count1 + 1)]
lis2 = [str(i).zfill(2) for i in range(1,count2 + 1)]
for i in range(0,len(lis2),n):
print(''.join(lis2[i:i + n]))
print()
for i in range(1,n + 1):
temp = lis1[:i]
lis1 = lis1[i:]
print(' ' * (2 * (n - i)) + ''.join(temp))
后面一部分和数字直角三角形异曲同工
