* There was something that tried to create by changing the print function's stdout and stdin piping. this block that directs outputs to "less" was inaccurate. When the process is over, the pipe does not close, so tty crashes. to prevent this, instead of printing data with print in the function, I chose to list and print the data with pipe.
* If there is no package in the takeback process, the program was closing. whether this happened because there was no error or did not understand the problem. This error has been fixed as of the moment.
