如何使用for循环打印三角形

Question

我需要一些帮助才能解决这个问题，现在它只能垂直打印

height = int(input("Height of triangle: "))
for x in range(height):
   for y in range(height):
     print("#",end = '')
     print()

Answer 1

这是我的解决方案，它涉及使用累加器：

height = int(input("Height of triangle: "))
count = 0

for i in range(height-1):
    print('#' + ' '*count + '#')
    count += 1

print('#'*height)

Answer 2

height = 6

for rowIndex in xrange(height-1):
    row = [' ']*height            # yields array of size height
    row[0] = row[rowIndex+1] = '#'
    print (''.join(row))    # This makes string from array
print ('#'*height)          # Print lower side of triangle

你也可以删除第5行的“+1”以获得更多“前卫”三角形。
