Hello,
I am trying to deploy an app on google app engine using bottle, a
micro-framework, similar to flask. I am running on ubuntu which comes
with python 2.7 installed but GAE needs version 2.5, so I installed
2.5. I then realized I didn't use make altinstall so I may have a

The standard library function random.randint() seems to be quite slow
compared to random.random(), and worse in Python 3 than Python 2
(specifically that's 3.3a0 latest from Mercurial, and 2.6.6 that came
default on my Ubuntu install).
My test involves building a list of one million random integer

Not all variables are environment variables. Variables only become

I'm using matplotlib and I'm happy with it. Quick plotting is easy
using the pyplot interface, which resembles the popular software
package MATLAB. As your ambitions grow, matplotlib has many
sophisticated tools waiting for you.
