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

chunks = int(input())
size = int(input())



print(
    chunks * "#" + (size - chunks) * "." + " " + str(round(chunks / size * 100)) + "%"
)
