I found it.
Sry for disturbing you!!

I need help on solving the errors,

Script,

What causes these errors?
I don't know how to fix it!.

Please, don't start new thread. Keep the discussion in this thread. If the answer you get does not solve the problem, say so, don't start new thread.

what exactly you want to do with imp? You don't need it at all.
also what do you think this line data = imp.load_source('data', '', f) is doing?

I would suggest you read again on how you work with files (like csv files) in python. here is our tutorial: https://python-forum.io/Thread-Basic-Files

Note that there are number of issues with your script (that don't raise errors [yet]). For example:

• on lines 11-14 you create a csv file, then you completely overwrite it on line 16.
  
• use of global variables should be avoided

Sorry, but it solved some of the problems!.
I'll not do it again.

That is the thing. i was watching a tutorial.
I don't know what it does, but I haven't finished the script though.
If you want. let me know, ill link the tutorial.

also what do you think this line data = imp.load_source('data', '', f) is doing?

That also I don't know.

on lines 11-14, you create a CSV file, then you completely overwrite it on line 16.

No, I create register.csv in the lines 11 - 14.
and create another file, data.txt in line 16.
Doesn't it?

Yes, sorry, my error - with these long path names.

the imp (now depreciated and replaced with importlib) is used to import modules using module name. You don't need to use it in simple script like yours. In any case it is not intended to "load" data/csv/txt files. Open the csv/txt file in read mode (i.e. r). You may decide to use csv module to read it - it will make it more convenient, but not necessary. You can just read the file with e.g. read() or readlines() method.

Also, it's better to use with context manager, like on line 11. Use it also when creating data.txt

As a side note - if using csv/txt is not mandatory, you may look into using different format like JSON or even better - a real detabase like sqlite3 (support for sqlite3, which is file based database comes with python).

Lets put my script aside.
Now, I want to make a system. that stores data about students.
I'm storing data in a csv file.
I want to know all the commands when working with csv.(I want them clearly pls)
And all the commands when working with txt files.(Also clearly)

If you can link me these commands then,
I can script a new one without watching a tutorial. (So I can understand better!)

Then I want to know how to turn .py into .exe.
So that people cant edit the script/see the script.

There is a module in the standard library for working with CSV files: https://docs.python.org/3/library/csv.html. You really should familiarise yourself with the standard library docs if you haven't already.

Also, why do you want to stop people reading your script? Who'll be using it anyway? As for stopping edits, can't you just use whatever your OS has for managing permissions? Looks like you're on Windows, so I can't help further with that.
