Write a complete Python program with prompts for the user to get the main text file (checks that it exists, and if not, output an error message and stop), for any possible flags (flags allows the user to change the default conditions or to use the defaults, and for any other input that this program may need from the user: split has an option of naming the smaller files. Your program will open the input file once only and using seek(0) to avoid re-opening the file will cost you all points for that part! middle list the middle lines of the file by skipping the first 5 lines (default) and skipping the last 5 lines (default) in order of the given text file flag: # change the number of lines to skip at the top and bottom Comment: If the file has less than 2 times the number of lines to skip, output the entire file. tail_head list the last 5 lines (default) in order first and the first 5 lines (default) second in order of the given text file flag: # output # lines instead of 5 (default) lines Comment: If the file has less than 2 times the requested number of lines, output the entire file in the order requested split split a text file into smaller files (may be useful with the FTP Project) flags: # put # lines of text into each output file (default=1000 lines) input: file file to be split (note extension and use it on split files) name file of newfiles (example: name-aa.ext, name-ab.ext, etc.) name may be blank, so the files are: xaa.ext, xab.ext, etc. (letters only, no numbers) note: your program generates the file names no external file of names allowed! Comment: Output the name of the file as it is being created and filled
