[smabubakkar]

Hi ,

I have created a python program based on Tkinter to compare two text files, i need display line number before every line. now i have solution but with this solution alignment will be a problem. I am attaching my code and screen shot of application.
my current solution is i am inserting line number at the beginning of the line as part of the text. i need a better solution

kindly help me.

alignment will be a problem

Not sure what this means but I would use a Listbox for each column (sorry don't know anything about the Text widget). Also, see Vegaseat's solution using Treeview at https://www.daniweb.com/programming/soft...-in-python
