I'm not even bothered by self As mentioned by Simown and atraub, it's better to be explicit than implicit.

It's easier to explain self in Python than this in C++/Java to students not familiar with object oriented programming. In C++/Java, it seems like voodoo, seemingly coming out of no where, where as in Python, It's right there.

Indeed, referring to self is quite common. But variables local to a method don't belong to the object, nor are they global.

public class Example {
   String name;

   public void method() {
      String name;

      name = "Where do I live?";
   }
}

Which variable is assigned the string assigned to? The answer to the question is irrelevant, what's relevant is that it had to be asked. In Python though...

class Example(object):
    def method(self):
        name = "Where do I live?"

There's no ambiguity. That's a local variable, without a doubt. Less wondering is a good thing

You're appending the product to another list. If you return x instead, you'll get the output you want. Note that you aren't using initMatrix effectively, regardless of this change.

I'm pretty sure import medical works in Python.

Awesome. Shall we name ourselves the Low Vitamin D club?

Hmm, basically the only time I'm not on a computer is when I'm sleeping or having meetings. Even then the meetings often involve a laptop.

I'm on a computer all day at work, all night at home doing university work, on my phone when travelling to and from these places.

Occasionally I watch movies and such with my girlfriend, but our media server has a keyboard, so it's still a computer

I swear I'm going to need a tablet or something in my coffin when I die. How else will I keep up with the news!?
