Write Python code that prompts the user to enter a telephone number in the form $($xxx$)$ xxx$-$xxxx and then reformats it and prints it out in the form xxx$.$xxx$.$xxxx$.$

For example:

$>>>$ Enter a phone number $[($xxx$)$ xxx$-$xxxx$]$: $(305)867-5309$

The reformatted phone number is: $305\mathrm{.}867\mathrm{.}5309$
