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 -h
usage: 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.
