[Solved] wc (word count)

https://www.youtube.com/playlist?list=PLhOuww6rJJNOGPw5Mu5FyhnumZjb9F6kk

Write a Python implementation of wc (word count). The program should print lines, words, and characters for each input. Files are acceptable arguments:

$ ./wc.py ../inputs/fox.txt       1       9      45 ../inputs/fox.txt

As is “standard in” (STDIN) if given no arguments:

$ cat ../inputs/fox.txt | ./wc.py       1       9      45 <stdin>

If given more than one file, also include a summary for each column:

$ ./wc.py ../inputs/*.txt    1000    1000    5840 ../inputs/1000.txt     100     100     657 ../inputs/1945-boys.txt     100     100     684 ../inputs/1945-girls.txt     865    7620   44841 ../inputs/const.txt    2476    7436   41743 ../inputs/dickinson.txt       1       9      45 ../inputs/fox.txt      25     278    1476 ../inputs/gettysburg.txt      37      91     499 ../inputs/issa.txt       9      51     248 ../inputs/nobody.txt       1      16      66 ../inputs/now.txt       2       9      41 ../inputs/out.txt       6      71     413 ../inputs/preamble.txt    7035   68061  396320 ../inputs/scarlet.txt      17     118     661 ../inputs/sonnet-29.txt    2618   17668   95690 ../inputs/sonnets.txt       3       7      45 ../inputs/spiders.txt       9      34     192 ../inputs/the-bustle.txt   37842   48990  369949 ../inputs/uscities.txt     176    1340    8685 ../inputs/usdeclar.txt   52322  152999  968095 total

The program should respond to -h and --help with a usage:

$ ./wc.py -husage: wc.py [-h] [FILE [FILE ...]]Emulate wc (word count)positional arguments:  FILE        Input file(s) (default: [<_io.TextIOWrapper name='<stdin>'              mode='r' encoding='UTF-8'>])optional arguments:  -h, --help  show this help message and exit

Run the test suite to ensure your program is working correctly.
