I wrote a small application in python-tk, and you can indeed do this #define boxes namebx = Text(window, height=1, width=20) officebx = Text(window, height=1, width=20) With the main project (parts are work in progress) here https://github.com/zleap/AboutMe hope this helps regards Paul -- https://mail.python.org/mailman/listinfo/python-list
Trying to read in data for a file to a python application
Hi I have been trying to write a small application that is essentially user information application. https://raw.githubusercontent.com/zleap/AboutMe/master/Aboutme.py So far I have managed to write the data generated to a file, what I want to do now, is read this data back in when the user opens the program. Trying to use https://stackoverflow.com/questions/3277503/how-to-read-a-file-line-by-line-into-a-list with open(fname) as f: content = f.readlines() # you may also want to remove whitespace characters like `\n` at the end of each line content = [x.strip() for x in content] Trying to use this as a guide (hence my code is a little different). But am really stuck So far the GUI window appears but no widgets. So something is clearly getting stalled. To begin with If I can read the text in, and just display in the console this is a start, I can then see if I can figure out how to take that and insert the data in to the right places. Can anyone help please. Thanks Paul -- https://mail.python.org/mailman/listinfo/python-list

I will do as suggested and create a Python program to read / write then move on to integrating that in to the main program. Thanks again Paul -- https://mail.python.org/mailman/listinfo/python-list

I asked about a tkinter app for a project I am working on a while back ,
what was suggested (which was a very useful suggestion) is get the
routine and feedback working without the GUI first, so in this case a
simply python program would ping something ever 5 mins and say if this
was successful or not.
Not sure if you would ping as such, but if you can get a normal python
script to do what you want, then you can add a gui later.
hope this helps
