Surely that's where you mount cdroms *from*? I can't think that

Oops, yes, that should be /usr/cdrom, sorry.

[Tutor] Newbie Programming puzzles, etc.

[Seekker]

Unfortunately, most of them seem to be aimed at people who aren't 
newbies. I think the world needs a good set of programming puzzles for 
beginners.


It would sure be helpful to have a library of newbie type projects ... I'm 
teaching myself with the "think like a computer scientist' books, and thus far 
 I've been able to follow and/or figure out the exercises ... 
but I'm only in chapter 03 at time moment.  I'm sure it'll get more challenging 
as I go.  I'm not the greatest 'problem solver' ... I've been hoping that 
learning a programming language would help in that area.

Thanks

Before you convert to an ImageTk, you need to first create a toplevel
window:

import Image
import ImageTk
import Tkinter as tk

root = tk.Tk()
#put your code here

And that should work. You'll still have to add the widgets and what-nots so
you can present your image, but in order to create an image with ImageTk,
you need to have a toplevel window created.

That's what this is telling you

Re: [Tutor] Hi

[Glen Clark]

Luke,

I used a video from Lynda.com, simply because I already had a
subscription. The price was about $25 per month which I think is more
expensive that showmedo. Or you could buy it for $99 (Python 3 Essential
Training (DVD-ROM)). 

The video's were very good for me personally because he was straight to
the point which kept me from getting bored. 

I have recently found showmedo though and they does loog very good also.
It seems to have a lot of content on there.

Regards, 
Glen

Also, if you have not yet chosen an IDE I recommend eclipse with the
pydev extension. Google them or if you use gnu/linux (like ubuntu) you
can get it from the package manager. It is a very simple interface, with
syntax highlighting, debug mode and console.

Re: [Tutor] Displaying Pictures & Text

[Patty]

Thank you!  I was getting confused, I thought I wouldn't need Tkinter.  I 
thought Tkinter is yet another addon library besides PIL.  Am I right or wrong? 
 So I actually need both?  And this brings me back to my _other_  question 
which is that as individuals go about downloading these addon libraries and 
their doc, how do you organize this on your computer system?   I can imagine 
that in corporations there are guidelines for this, but I am wondering what you 
all do? You could end up with addon libraries, doc and Readmes all over your 
hard disk

Re: [Tutor] Programs for Newbies?

For my first program, I liked creating a number game, simple and where the 
user made a choice.  That was good for learning how to interact with the 
user.  The raw_input() function.

Hi all,

Any suggestions for a newbie to program while learning python?  I am new 
to

programming and python.



Here's a few suggestions:


Write a program that asks the user to enter a word, then counts how many 
vowels and consonants are in the word.


Write a program that asks the user for a list of numbers, separated by 
spaces or commas, and then calculated the average.


A program that prints the time.

A program that prints how many days to go until their next birthday.

A program that counts how many palindrome numbers there are between two 
other numbers. (A palindrome number is one like 12321, or 473374.)


A program that sings (well, prints) the "There were ten in the bed" song. 
If you don't know it, it is a children's song. You start off by holding up 
ten fingers, or you can use actual children. You don't have to start with 
ten. Then you sing:


There were ten in the bed, and the little one said,
Roll over! Roll over!
And they all rolled over and ONE FELL OUT!
There were nine in the bed, and the little one said,
Roll over! Roll over!
And they all rolled over and ONE FELL OUT!
There were eight in the bed, and the little one said,
...

Well you get the idea. Eventually you've left with only the little one 
left, and the song ends:


There was one in a bed, and the little one said
Good night!

Yes PUIL is for transforming the graphics and creatnf the image

Most common add-on libraries will install themselves in the
site-packages dirtectory structure under your Python root folder
So they remain fairly well organized.

Some thoird party tools are kist a single python module and you have
to decide where to put it yourselfd. In my case thats usually in
site-packages too.

This does mean that when you upgrade you have to decide which,
if any, of your site-package files to migrate to the new version and
which to re-download. I usually opt for the re-download route just
to be safe.

My favorite one is a simple guessing game, where the computer "thinks" of a
number 1-10 (inclusive) and then the user guesses the number, with the
computer responding "Too High" or "Too low!".

For more variation, keeping "score" - number of guesses, # of rounds played,
etc. are fun additions to the program.

Tkinrer is quite easy once you get the hang of it.
Its also a good intro to GUI frameworks in general if you ever
need to move top something more advanced.

There are good tutorials for both PIL and Tkinter on
the Pythonware site:

http://www.pythonware.com/products/pil/index.htm

http://www.pythonware.com/products/tkinter/index.htm

Or you can try the intro to GUI programming in my tuitorial.

Re: [Tutor] Hi

[trench]

I'd also point out that Google has created a very awesome Python course
which is heavily dependent on video lectures by Nick Parlante. Included in
the course are downloadable exercises and examples (all mentioned in the
video lectures). After you review all of this quality (not to mention free)
material... I think you'll fully understand what separates Google from its
competitors. (By this, I simply mean that you will not see similar offerings
from, say, Facebook, Apple, or MS.)

http://code.google.com/edu/languages/google-python-class/index.html

This is
a part of Google's "Google Code University". Here's the root URL for the
entire project: http://code.google.com/edu/  -- definitely worth checking
out.
