Making shapes from user input
<p>The program should get two numbers from the user. The first number is the amount of triangles. The second number is the amount of rows per triangle. </p>

<p>It's based off a square problem we just did which is</p>

<pre><code>numRows = input('Please enter the number of rows: ')
numRows = eval(numRows)
numAst  = 1 
for i in range(numRows):
    print(numAst*'*')
    numAst += 1
</code></pre>

<p>I can not for the life of me figure out how to get it to make triangles though. I know I need some sort of outside loop to restart the inner loop, but I'm not sure how to go about that?</p>
