Portably generating infinity and NaN

What's the best way to portably generate binary floating point infinity and NaNs? I only know two solutions: 1. Using the fpconst module proposed in IEEE 754, which I believe shifts bits around. 2. Using an extension module (for example, numarray.ieeespecial will do it). I thought of using flo

Re: Newbie help with array handling

""" Since you are a beginner and since RCCILA (Runnable, Commented Code Is Least Ambiguous) I'm proving this example code to help you get used to manipulating data with python. This should give you an idea of how to juggle a bit. After you learn how to do this you likely still will not be

Inconsistent result from urllib.urlopen
