Part 1 45 points head-tail = 10 pts, splits 20 pts, and wc = 15 pts. 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 (including none), 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 (opening it for the program wc more than once will you cost ALL for this section!). list the first 10 lines (default) and the last 10 lines (default) in order of the given text file head_tail flag: output # lines instead of default lines Comment If the file has less than 20 lines (default), output the entire file split flags split a text file into smaller pieces put # lines of text into each output file (default= 1000 lines) input file name file to be split (note extension and use it on split files) file of newfiles (example: name-aa.ext, name-ab.ext, etc.) name may be blank, so the files are: xaa.ext, xab.ext, etc Comment: Output the name of the file as it is being created WC count characters, lines, and words in a text file output order: lines words characters
