how can I generate a password in hashlib

when using with context manager, you don't need to call close(), i.e. you don't need output_handler.close()

And please, stop this nonsense about the extra empty line. You must understand that every line end s with new line character. So what you see as elham,9770 is in fact elham,9770\n. That's the correct thing to have. As a result there is what you see as empty line. THAT IS NORMAL. In your other thread https://python-forum.io/Thread-Avoiding-...s-csv-file perfringo asked you some question trying to explain this to you. Think what will happen if you don't have new line char at the end of last line with data and you or some one else want to append new data. You will append on the last line, not as a new line. Line ALWAYS end with newline character
