Comments on: Clever use of Python’s complex number type http://bob.pythonmac.org/archives/2005/01/29/clever-use-of-pythons-complex-numbers/ Bob's Rants Thu, 24 Jul 2008 01:18:29 +0000 http://wordpress.org/?v=2.5.1 By: hunterp http://bob.pythonmac.org/archives/2005/01/29/clever-use-of-pythons-complex-numbers/#comment-78 hunterp Mon, 31 Jan 2005 22:42:09 +0000 /?p=94#comment-78 i looked at check “Manipulate simple polynomials in Python” by Rick Muller http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/362193 and its sort of what i mean. but maybe he didnt know the eval trick used above since half of the code is dedicated to parsing. I will point to this discussion on there. i looked at

So just create a simple class to deal with __pow__ __mul__ __div__ __sum__ __sub__ and you could use eval to reduce any equation into condensed form. Has anything like this been done ? It seems trivial I see the trick in this example to be the use of eval’s third argument.
