How to get hex string from signed integer
<p>Say I have the classic 4-byte signed integer, and I want something like
<p> print hex(-1)
<p> to give me something like
<p>>> 0xffffffff
<p> In reality, the above gives me -0x1. I'm dawdling about in some lower level language, and python commandline is quick n easy. 
<p> So.. is there a way to do it?</p>
