import math
import sys# Auto-generated code below aims at helping you parse
# the standard input according to the problem statement.zreb = int(input())mylist = []
for i in range(1, zreb):mylist.append(i * "* ")
mylist = [item.rstrip() for item in mylist]print(*mylist, sep="\n")
print((zreb * "* ").strip())
# mylist倒叙
print(*mylist[::-1], sep="\n")

来看一种更优雅的解法（作者：FrancoRoura）

import sys
import math# Auto-generated code below aims at helping you parse
# the standard input according to the problem statement.asd = int(input())
for i in range(1,asd):print(*["*"] * i)
for i in range(asd,0,-1):print(*["*"] * i)

print(*["*"] * i)
这里注意["*"] * i这个是i数个列表，比如i=3就是["*"]["*"]["*"]，然后左面的*解包为参数，相当于print(*,*,*)，而print默认是中间空格(这样也是刚好解决了最后面空格的问题)，所以刚好解决

h = 0
s = 0

for i in range(n):snake = input()if "-<" in snake or ">-" in snake:h += 1else:s += 1
print(f"{round(h/(h+s)*100)}%")
