I open terminal and type "python", then the following: >>> import serial; >>> ser = serial.Seri...

I'm trying to use URLLIB2 to open a URL and read back the contents into an array. The issue seems to be that you cannot use string interpolation in a URL that has formating characters such as %20 for space, %3C for '<'. The URL in question has spaces and a bit of xml in it. My code is pretty simple, looks something like this: #Python s...
