#91692 — lotto number generator

Hi.
I am new to python so am still in learning phase.

I was thinking to make one program that will print out all possible 
combinations of 10 pairs. I think this is a good way for something 
"bigger" :-).

This is how this looks like:

1.) 1 2
2.) 1 2
3.) 1 2
4.) 1 2
5.) 1 2
6.) 1 2
7.) 1 2
8.) 1 2
9.) 1 2
10.) 1 2

So, i want to print out (in rows) each possible configuration but for 
all 10 pairs.

example:
1 1 1 2 2 2 2 1 1 1
2 2 2 1 1 1 1 2 2 2
1 1 2 2 1 1 2 2 1 1
etc.

What would be the best way to make something like this ?
Maybe some tutorial ?

The Python tutorial is a good place to start:

    https://docs.python.org/3.4/tutorial/index.html

For your particular problem you'll probably want to use the
itertools.product function:

    https://docs.python.org/3.4/library/itertools.html#itertools.product

I wouldn't recommend printing out every possible combination to the
screen, though. That's over a million rows! Start with fewer pairs (4
is probably good), or write them to a file instead.

Er, actually it's just 1024, so that isn't so bad. You probably still
don't want all that in your terminal, though.
