使用字母打印 rangoli 图案的 Python 程序
假设我们有一个数字n。我们必须创建nxn大小的字母rangoli。n必须在1和26之间，当n为26时，它将从a开始到z结束。
所以，如果输入像5，那么输出将是
--------e-------- ------e-d-e------ ----e-d-c-d-e---- --e-d-c-b-c-d-e-- e-d-c-b-a-b-c-d-e --e-d-c-b-c-d-e-- ----e-d-c-d-e---- ------e-d-e------ --------e--------
示例
让我们看下面的实现来更好地理解
def solve(n):
for i in range(n-1,-1,-1):
for j in range(i):
print(end="--")
for j in range(n-1,i,-1):
print(chr(j+97),end="-")
for j in range(i,n):
if j != n-1:
print(chr(j+97),end="-")
else:
print(chr(j+97),end="")
for j in range(2*i):
print(end="-")
print()
for i in range(1,n):
for j in range(i):
print(end="--")
for j in range(n-1,i,-1):
print(chr(j+97),end="-")
for j in range(i,n):
if j != n-1:
print(chr(j+97),end="-")
else:
print(chr(j+97),end="")
for j in range(2*i):
print(end="-")
print()
n = 8
solve(n)输入
8输出结果
