Press button to load data

[jim-on-linux]

Just from a glance my thoughts are to 
start with one file and build on it. Make 
a class of it so you can loop it to use 
it over for each record.


You wrote that the info was in a file on 
the hd. If it is in a file on the hd, use the 
open() 
function, read from the file, only one record
and write the data to a list. 
   
You can incorporate the 
button option, 

"command = CallSomeFunction",

to call a function that builds a window,  
and loads the data into labels or
entry boxes.
If you are going to modify 
the data, entry boxes allow you to  
modify it and save it back to a 
file.

Also, when using the open() function,
close it after you get the data you need. 
otherwise you may experience 
unexpected problems.

client = open('client', 'r')
client.read() (readline()) (readlines())
client.close()
