Error when compiling simple python program
<p>This script won't compile. I wanted to made a simple 21-style game for practice but I get an error: </p>

<pre><code>X@X:~/Desktop$ python 21.py File "21.py", 
line 18 
int(ptotal) = ptotal + newcard 
SyntaxError: can't assign to function call
</code></pre>

<p><a href="http://pastebin.com/mfc64c2d" rel="nofollow">Here's the code</a>. Can anyone please help me? I'm obviously a beginner and the code is pretty sloppy.</p>
