Code - what could be done better?
Hi all,
here's the main code of thc, my txt to html converter. Since I'm a
beginner it is far, far, faaar away from perfect or even good :-)
What could be done better?

What would YOU like to see in a txt to html converter?
As you might have mentioned I'm just working on a txt to html converter called thc. This project is intended for me to learn Python and now pyQT4 to which I changed a few days ago (started with Tkinter). I have implemented the following features so far: - Giving a title for the html - Choose whether it's Transitional or Strict Doctype - Select a background color - Show the converted file with the standard browser - Working on a font size slider I don't really know if this is of any use for anybody but it's just a fun project by a beginner :-) Now I'd like to know what kind of features you'd like to see in version 0.3 of thc!? Please post them... Have fun! Listick http://www.lictick.org -- http://mail.python.org/mailman/listinfo/python-list

Florian Please post them... Florian Have fun! Florian Listick Florian http://www.lictick.org You could learn something from emacs-muse. That plugin can help emacs to convert txt to html, tex, pdf, docbook and some other document format. In emacs-muse, the title and subtitle is defined like this: *emphasis* **strong emphasis** ***very strong emphasis*** _underlined_ =verbatim and monospace= emacs-muse : http://mwolson.org/projects/EmacsMuse.html Thank you for this information. I already thought of using dots or asterisks or whatever to let the user format the text instead of using html tags (this would be quite paradox ;-) Please keep on posting ideas...

I am not sure of this is the right place to ask a question about the

why is the printed result of
basket = {'apple', 'orange', 'apple', 'pear', 'orange', 'banana'}
print(basket)
{'orange', 'banana', 'pear', 'apple'}
in the sequence given?
A set is not ordered and eliminates duplicate elements. So the output is
random in terms of the order and only shows each single item once...
Correct me if I'm wrong :-)

Re: hex(dummy)[2:] - issue...
Tim Chase wrote: I need some advice :-) I'm using hex(dummy)[2:] to represent a color in hexadecimal format for the bgcolor in an html file. dummy is the color value in RGB of course... Now, if there's an R, G or B value of zero, this command only prints one single 0 instead of two. What's wrong with the code? You can try PLACES = 2 # 6? hex(dummy)[2:].zfill(PLACES) Alternatively, you can output decimal numbers in HTML/CSS with rgb(r, g, b) such as style=rgb(255,0,0) However, I recommend doing this via CSS unless you have a strong reason to sully your HTML with style information. -tkc hey tkc, I used your first alternative. This did it! Thanks a lot. I think I will write the style stuff into a .css file in the next few days but until then I'm just working on get my program to work...

Incidentally, the language in an HTML DOCTYPE refers to the language of the
DTD, not
the document. It's never correct to use //DE in an HTML page, unless you have a
custom
(German) DTD. So the code can be improved further by cutting that part out.
strict_or_transitional = {True: 'Transitional', False: 'Strict'}
# this assumes that isChecked() returns True or False
spec = strict_or_transitional[self.rdioBtnTransitional.isChecked()]
doctype = '!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.0 %s//EN\n' % spec
Yes, that's true. I missed that. Thanks for the information.
And many thanks to Stefan.

thc v0.3 - txt to html converter - better code?
Hi all,
here's some code of thc, my txt to html converter programmed with Python
and pyQT4:
---
if self.rdioBtnTransitional.isChecked():
if self.cmboBoxLang.currentText() == English:
file_open.write('!DOCTYPE HTML PUBLIC -//W3C//DTD
HTML 4.0 Transitional//EN' + '\n')
elif self.cmboBoxLang.currentText() == German:
file_open.write('!DOCTYPE HTML PUBLIC -//W3C//DTD
HTML 4.0 Transitional//DE' + '\n')
else:
file_open.write('!DOCTYPE HTML PUBLIC -//W3C//DTD HTML
4.0 Strict//EN' + '\n')
if self.cmboBoxLang.currentText() == English:
file_open.write('!DOCTYPE HTML PUBLIC -//W3C//DTD
HTML 4.0 Strict//EN' + '\n')
elif self.cmboBoxLang.currentText() == German:
file_open.write('!DOCTYPE HTML PUBLIC -//W3C//DTD
HTML 4.0 Strict/DE' + '\n')
Do you have any ideas for a better code than that? Could this be done
smarter, shorter, whatever!?
