I think my peanut sized brain is starting to understand how to do this. I
tried with a simple dice game where 4 dice are rolled, if the total of the

when only 2 are needed but I wanted to prove to myself I could cal
better at reading the code.
Very good point. I have to go away for 3 weeks in a couple of days and I was

Because the module is named
hat randint is in the random module.
ie, instead of calling randint(), call random.randint().
Have you been through the tutorial on python.org? It is quite helpful.

Have you tried restarting IDLE? The first thing to do would be to
verify that the problem is what you think it is (as opposed to a bug
in your code, for example).

d a
function definition with an extra carriage return.
(at least, that's the way it works in the console version)
eg:
>>> def foo():
... pass
... def bar():
File "", line 3
def bar():
^
SyntaxError: invalid syntax
random numbers
between 1 and 44 inclusive
print games, lotto
print
else:
print
print "Hope you win!"
I know this is a very simple program but... could I have done this a better
way?

G'day, I'm new to Python and new to the list and just thought I'd say a quick hello before asking my 1st dumb question. My name is John and I live in Australia, I've been using computers since about 1983. I haven't done any programming since the commodore 64 basic days
database files. I can see the database files in the
dist folder.
Are there other files which I have to manually copy into the dist folder
such as the sql_mar.py?
Any help or pointers would be greatly appreciated. I know that this is a
py2exe specific question but I have
programming with a GUI, one good way
is to use .after_idle.
ie, instead of myturns.insert(str(i)), do
top.after_idle(myturns.insert, str(i)) (I think this is the right
syntax). This will cause the mainloop thread to run the code instead.
HTH!

, for instance:
>>> n = 'xb1jyzqnd1eenkokqnhep6vp692qi9tmag3owzqw0sdq3zjf'
>>> n[0:3], n[3:6]
('xb1', 'jyz')
Can you see how to generate the slice boundaries for the length you need?

song ranked 50 will be fifty times more
likely to be chosen than a song ranked 1, while a song ranked 80 will
be only 1.6 times more likely to be chosen than a song ranked 50.
Maybe some kind of logarithmic transform might smooth things out a
bit..?
