Do you want your text editor to use a GUI or be console based ? If you want to make your own file format, then you will need to make a specification for extension. If you want I will help you code your text editor.

It sounds like I want to do something similar to danesh1354. I want to create a lightweight text editor written in Python that uses a custom file format. Fabez, would you mind pointing me in the right direction too?

First does it make sense to customize or learn from any of these text editors:

PyQT4 Text Editor (a tutorial in three parts)
Simple text editor in PyQT4
Extending PyQT4 text editor
PyQT4 Text editor - final changes

PyWord
PyWord/pyprime Homepage - PyWord and pyprime

Edge (a joking and/or simple version of PyWord)
edge source code - PyWord and pyprime

Txtinator
Txtinator - a text editor written in Python - Blender Artists Forums

Code for a text editor posted to ubuntuforums
Python Text Editor help - Page 2 - Ubuntu Forums

There are a few different GUI toolkits represented (QT4, Tkinter, wxPython). Does anyone have any recommendations? Are some better for certain purposes?

Finally, does anyone have any tips on getting a text editor to read from and write to a custom file format, probably XML-based.

Thanks.

I prefer wx. But there is really no big difference between GTK+, Qt and wx. Feature and maturity wise. Tk however is slightly different. And personally i dont like it.

But what you should use is really up to you. Take a quick check on there documentation and some sample code and go with the one that suits you the best.
