Drawing a right triangle with loops
<p>I have spent the last half hour playing around and I still don't know how to make it so a character is added each time it loops. 
This picture can better explain it better of what I mean.</p>

<p>here's my code:</p>

<pre><code>triangle_char = input("Enter a character: \n")

triangle_height = int(input("Enter triangle height: \n"))

for row in range(triangle_height):
    print(triangle_char)
</code></pre>
