Dear List;

I have embarked myself into learning Python, I have no programming
background other than some Shell scripts and modifying some programs in
Basic and PHP, but now I want to be able to program.

I have been reading Alan Gauld's Tutor which has been very useful and I've
also been watching Bucky Roberts (thenewboston) videos on youtube (I get
lost there quite often but have also been helpful).

So I started with an exercise to do sequences of letters, I wan to write a
program that could print out the suquence of letters from "aaa" all the way
to "zzz"  like this:

So far this is what I have:
letras =
letra1 = 0
letra2 = 0
letra3 = 0
for i in letras:
    for j in letras:
        for k in letras:
            print letras[letra1]+letras[letra2]+letras[letra3]

It goes all the way to aaz and then it gives me this error
Traceback (most recent call last):
 File "/home/administrador/programacion/python/letras2.py", line 8, in
print letras[letra1]+letras[letra2]+letras[letra3]
IndexError: list index out of range
Script terminated.

Am I even in the right path?
I guess I should look over creating a function or something like that
because when I run it I can't even use my computer no memory left

¡Saludos! / Greetings!
