Hello my friend;

Please, i want to ask you about text files management.

In fact, i am creating a text file and add some lines when i click on a button.

But, i want to empty the file before than add lines because the function thats adding lines is functional each time that i press the button.

Please, who can help me know how to empty my text file in Python.

Thanks a lot in advance.

Regards.

Finally, i got the answer.

Here is it:

filename="/opt/file.txt"

lines = open(filename).readlines()  

open(filename, 'w').writelines(lines[-1:-1])

Regards.
