python string input problem with whitespace!
<p>my input is something like this </p>

<p>23 + 45 = astart</p>

<p>for the exact input when i take it as raw_input() and then try to split it , it gives me an error like this </p>

<p>SyntaxError: invalid syntax</p>

<p>the code is this </p>

<pre><code>k=raw_input()
a,b=(str(i) for i in k.split('  +   '))
b,c=(str(i) for i in b.split('  =   '))
</code></pre>

<p>its always number + number = astar</p>

<p>its just that when i give number+number=astar i am not getting syntax error ..!! but when i give whitespace i get sytax error </p>
