Write a program that will substitute all the vowels in a given text with a single vowel (default “a”):

$ ./apples.py 'The quick brown fox jumps over the lazy dog.'Tha qaack brawn fax jamps avar tha lazy dag.

The -v or --vowel can be use to specify another vowel:

$ ./apples.py 'The quick brown fox jumps over the lazy dog.' -v iThi qiick briwn fix jimps ivir thi lizy dig.

The program should reject a --vowel that is not a vowel (a, e, i, o, u):

$ ./apples.py 'The quick brown fox jumps over the lazy dog.' -v xusage: apples.py [-h] [-v str] strapples.py: error: argument -v/--vowel: invalid choice: 'x' (choose from 'a', 'e', 'i', 'o', 'u')

The argument may name a file in which case you should read the contents of that file:

$ ./apples.py ../inputs/fox.txt --vowel uThu quuck bruwn fux jumps uvur thu luzy dug.

Given no arguments, the program should print a brief usage:

$ ./apples.pyusage: apples.py [-h] [-v str] strapples.py: error: the following arguments are required: str

Or a longer usage for -h or --help:

$ ./apples.py -husage: apples.py [-h] [-v str] strApples and bananaspositional arguments:  str                  Input text or fileoptional arguments:  -h, --help           show this help message and exit  -v str, --vowel str  The vowel to substitute (default: a)

Run the test suite to ensure your program is correct:
