Note: I'm struggling to follow your code whilst reading on my phone so the following suggestions make no reference to your particular codebase
Okay I understand. Perhaps it doesn't matter.
Let's first assume that all buttons could be pressed in any order, therefore given the following presses: but1, but2, but2, but3, we will have the first line with hi_1, the second line empty and the third line hi_3. Now I also assume that there >is no 'update file' button, therefore each press of a button needs to update the file making a change to a single line. That sounds to me like a good use for an update_file function that accepts a parameter of which line should be updated. >So the main challenge is to write a function that can read/write to a file certain data depending on the argument passed. The function should:
Read file Identify line to be changed If line empty Change line to hi_# Write file
When you open a file, you could then use the read function to read the whole file, or you could use the readlines function to read the file line by line. Experiment with both, see what data types they both return and decide which is most >suitable. Bear in mind you need to easily differentiate each line and access them individually.
If your still struggling to write this function, show us how far you get and we can go from there.
Actually, I nearly know how do to solve this problem. I just have one problem. Can I use writeline() to write text into line 3 or line 5 for example? Say that I want to write the text "hi" into line five of a text file, can I do this using writeline(), if so, how ?
Thanks for the response! Hope this helps, Bodsda Sent from my BlackBerry® wireless device _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
