I do not know the file name at the time of coding. As I get data, it will be stored as "user.txt" Now I need to fill in my code the path and the filename once. Now I shall read the file, process it and save many output files as "useroutput.txt", "useroutput.jpg", and so on. in the same path as the data file. I don't want to keep editing each and every place and time.
How can I do this? Any help is appreciated. Thank you for your time.
