输入的数做直角三角形

反三角形：

height = int(input("the height is>>"))
num = 1
while height>0:
    h = height
    while num <= h:
        print("#",end="")
        h -= 1
    print()
    height -=1

 

 

正三角形：

height = int(input("the height is>>"))
num = 1
h = 1
while num <= height:
    h = num #让h永远等值num，与循环后的v无关
    while h > 0:
        print("#",end="")
        h -= 1
    print()
    num +=1
