I'm trying to set up a Matlab like environment so I downloaded the latest version of python(x,y) with all the modules that come with it and downloaded python 3.4.1. Does python(x,y) not run the latest version of python? I noticed because the python(x,y) shell doesn't auto calculate mathematical operations into floats which I read is a difference between python 2.x and 3.x. How do I fix this problem or is there any alternative solution?
