Challenge 138 - Length of Worm

Given a string worm create a function that takes the length of the worm and converts it into millimeters. Each - represents one centimeter.

Examples

worm_length("----------") ➞ "100 mm."

worm_length("") ➞ "invalid"

worm_length("---_-___---_") ➞ "invalid"

Notes

• Return "invalid" if an empty string is given or if the string has characters other than -.
