Complete the get_valid_word() function that takes no parameters. The get_valid_word() function prompts the user to enter a word. The word must start with the letter "d" and end with the letter "r", both lowercase. While the user does not enter a valid word, the function informs them of their error and prompts them again. When the user does enter a valid word, the function returns it.

For example:
