In python:

Write a program that takes a sentence with two adjectives describing an animal and reverses the adjectives, using regular expressions, and then outputs the new sentence. The sentence that it must read in should be of the following format, where the two adjectives are separated by a comma and a space:

The quick, brown fox jumped over some other non-descript animal.

If that previous sentence was the input, then the program output should look like:

The brown, quick fox jumped over some other non-descript animal.

Note that everything is identical between the two sentences except for the adjectives switching places. You may make up your own sentence, as long as the adjectives are formatted as in this example. Remember, don't make your regular expression match this exact sentence it should work with any other input sentence with comma-separated words like this.
