求python大佬用双重for循环打印一个倒等腰直角空心三角形，5行5列的如图，在线等急急急
按照你的要求编岩差写的用双重for循环打印一个倒等腰直角空心三角形的Python程序如下桐枣乱
n=5
for i in range(n,0,-1):
for j in range(i):
if j==0 or i==n or j==i-1:
print("*",end='')
else:
print(" ",end='')
print()

Python实现输出“倒三角形”
输入正整厅族数 n = 20， 输出一个n层的倒三角形。例如，n = 5时输出如下：
分析题目找到规律，每一层输出的 # 号的个数为 2n-1，而空格的个数为 n-层数
str为字符串
str.isalnum() 所有字符都是扮闭弊数字或者字母态毕
str.isalpha() 所有字符都是字母
str.isdigit() 所有字符都是数字
str.islower() 所有字符都是小写
str.isupper() 所有字符都是大写
str.istitle() 所有单词都是首字母大写，像标题
str.isspace() 所有字符都是空白字符、\t、\n、\r
