Python 3.2 Tkinter and TTK
Just downloaded Python3.2 from python's site and attempted to run some of the examples in the 24.2.10Tk Styling. The button worked, but the menu didn't. I also tried a couple from the TKDocs web site. Only errors from there. So, what do I need to do to get it to run? -- http://mail.python.org/mailman/listinfo/python-list
Newby Question for reading a file
Simple question but I haven't found an answer. I program in ABAP, and in ABAP you define the data structure of the file and move the file line into the structure, and then do something to the fields. That's my mental reference. How do I separate or address each field in the file line with PYTHON? What's the correct way of thinking? Thanks! -- http://mail.python.org/mailman/listinfo/python-list

Hi Mike,
ABAP is loosely based on COBOL.
Here is what I was trying to do, but ended up just coding in ABAP.
Read a 4 column text file of about 1,000 lines and compare the 2
middle field of each line. If there is a difference, output the line.
The line's definition in ABAP is PERNR(8) type c, ENDDA(10) type c,
BEGDA(10) type c, and LGART(4) type c.
In ABAP the code is:
LOOP AT in_file.
IF in_file-endda <> in_file-begda.
WRITE:\ in_file. " that's same as python's print
ENDIF.
ENDLOOP.
I can read the file, but didn't know how to look st the fields in the
line. From what you wrote, I need to read each segment/field of the
line?
Thanks,
Steve

Peter, you are correct, just fields glued together. I did not know
there was a struc module and that code looks real good. This is
something I will use in the future. Thanks!
Curt, that looks good also. I just need to test the 2 middle values.
I didn't know how to store line.split values into variables and this
is simple. Thanks!
Again, thanks Mike, Peter and Curt. Now if you ever need to know
ABAP... ;)

Data Coding suggestions
Just learning Python and have a project to create a weekly menu and a shopping list from the menu. This is something I do manually now, so I'm automating it. What I'd like is a list of menu choices, such as: CODE- Description - Est Cost 'B01 - Pancakes, Sausage,and Eggs - $5.80, 'L01 - Tuna Fish sandwices and chips -$ 4.25 , 'D01 - Dirty Rice and Garlic Bread' - $5.70. >From the choices, I'll create a weekly menu, print the menu, and then print list of ingredients ( and sum the commom items) CODE- Item - Qty. - Unit B01 - pancake mix - 1 - box B01 - milk - .3 -gal B01 - eggs- 10 - each D01 - dirty rice mix - 1 - box D01 - milk - .3 - gal. I would like to expand the ingredient list to include other fields like 'last purchase date' and 'reorder point'. I've used an example program and started to code it but just realized I've been coding ABAP in Python, that is set up a data structure and use that. What I want is to learn code Python in Python. Question: How should I set up the data? I'm looking at maybe 70 menu items and maybe 1000 items for the shopping list. I need to be able to maintain each item also. I am using python 2.6 but would like to use 3.0. Thanks for any suggestions! -- http://mail.python.org/mailman/listinfo/python-list

While shopping today I've thought of a few more columns for my data so my first item will be building the 3 DB tables and a way to populate them. Since this was intended to automate what I do on a weekly basis, I didn't think about adding recipes since I know what I need for the family, but that's a good touch. Item 1. Build 3 db tables Item 2. Build app to populate tables. Item 3. Build app to read tables and print lists. Anything else? -- http://mail.python.org/mailman/listinfo/python-list

Henrik,
Welcome to the list. As a newbie myself, I ran into the Python3 vrs
2.6 issue. May I suggest starting with 2.6? There is many more books
and internet stuff you can learn with in 2.6 - and the examples will
work. As Garry wrote, once you understand 2.6, 3.0 will not be a
challenge.

Re: Language mavens: Is there a programming with "if then else ENDIF" syntax?
Along the COBOl line is ABAP, the 4gl language from SAP. If today = 'Mon'. message 'oh boy'. elseif today = 'Wed'. message 'Hump day'. elseif today = 'Fri'. message 'TGIF'. else. message 'get to work'. endif. The period is the statement teminator. Indentation and separte lines are just to make it readable. -- http://mail.python.org/mailman/listinfo/python-list
Blogger Widget web app
Please give me directions on where to start researching for answers. I probably can do the javascript, but I don't know where to start on the Python. 1. Wife has a blogger blog and wants a widget to embed in the posts. 2. Widget will have a form that readers can enter their name and url. 3. Widget also lists in numeric order the name and url of all the readers who signed up in that post. 4. Son has an old PC he turned into a server, and installed Windows IIS on it. What I need to do is to write the cgi scripts to send a list of names and urls for each post on load, validate the input from the form and store the results per blog post. If you have seen Mr. Linky, that's what I'm tring to mimic. This will only be for her blog, so she can have a faster load time and less down time. I have NO intention to build this for more than her. So very simple and easy is the key. I've read the mailing list, I just got the books, Programming Python by Mark Lutz and and Python Web Programming by Steve Holden. There is so much great info I don't know where to start or what I need to start with. Thanks for any pointers. Steve Oldner -- http://mail.python.org/mailman/listinfo/python-list

There are some free databases of codes, but they are dated. USPS and 3 party vendors sell zip code databases and lists. The USPS APIs are a joke. They were going to charge me for using them. I ended up using a 2 year old database of ZIP codes for my needs. Hope this helps! -- http://mail.python.org/mailman/listinfo/python-list
