python输出等腰数字三角形(python输出等腰三角形代码)
Python用while循环写一个等腰三角形
temp?=?input("打印几行：")
n?=?int(temp)
space=list('?'*(2*n-2))
mid=n-1
for?i?in?range(n):
????line=space.copy()
????if?i?!=?n-1:????????
????????line[mid-i]='*'
????????line[mid+i]='*'
????else:
????????line[:]='*'*(2*n-1)
????print(''.join(line))
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
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 等腰三角形 如何做程序？
def?triangle(n):
????s=''
????for?i?in?range(1,2*n+1):
????????if?i=n:
????????????s=s+'X'*i+'\n'
????????else:
????????????s=s+'X'*((n-i)+n)+'\n'
????print?s
if?__name__=="__main__":
????n=int(raw_input("please?input?triangle?len:"))
????triangle(n)
python 2.6.6测试，结果如题目要求
python使用for循环打印一个正立实心等腰三角形？
1、示例代码
def printTri():
for i in range(1, 7):
for j in range(1, (7 - i)):
print(' ', end='')
for k in range(1, 2 * i):
print('*', end='')
print()
printTri()
2、实例结果
