Re: [Tutor] Thanks for the advise to tutor! HTTP Error 400 resolved
I have added below to the first line of the function and managed to
ignore the space and solve it. Thank you for the hint!

That's not how it works. You post a question and the code and any error messages and we (collectively) try to help you.

[Tutor] (no subject)
I'm having a problem with my code on an interactive story. All the choices work until the end. When the code reaches the end, it will print different functions that aren't even set to be called in the code. I'm not sure what I've done wrong and can't ask anyone for help because they're learning the same rate as I am in my computer science class. If you would like, I can send you a link to my code on pythonroom.com. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

So how did you find it?
What do you hope to do with it?
BTW You sent this to me only,. you need to use Reply-All
or Reply-List to include the tutor list. I've CCd the list in this response.

So this apparently draws two green rectangles and a ball at
a random location.

This sets the frames per second timer to 20fps.

The previous two lines should be indented.
Indentation is critical in Python so you need to post
in plain text not HTML or RTF. Without the indentation
it gets difficult to tell what is going on.
But in this case it basically exits the program when
the KEYDOWN event is received. (Whatever KEYDOWN and
event mean in this context - I don't see them defined
anywhere.)

If q is pressed it draws another 2 balls. I have no idea why,
I never played pong...

More of the same kind of thing.

fpsClock.tic(FPS)

Its a game using PyGame.
Have you read the PyGame tutorial?
If not I suggest you start there and then try asking questions
on the pyGame forum, because almost all the code is PyGame
specific rather than generic Python.
> Does this makes any sense to anyone?
Sure, I'm sure a PyGame user would find it very straightforward.
You probably just need to do some research/reading.
But the big questions are:
- what is it supposed to do?
- What does it actually do?
- do you get any error messages? If so what?

I know the classroom environment is different, but in most professional programming environments you will be working collaboratively with a team and unless you've been told not to do so in class, if it's not an exam, working with peers is a great way to learn skills you will use forever. In the Open Source Software world there's a famous quote "many eyeballs make all bugs shallow" (Eric Raymond, "The Cathedral and the Bazaar", a free essay that will be worth a read someday. It's often referred to as Linus' Law). ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
