Shelf labels

#021StarterStrings3 min

The second-hand bookshop is making shelf labels. Some titles are all capitals, some have extra spaces at the ends. Write shelf_label(book): remove the spaces at both ends, then make each word start with a capital and the rest lower case. An empty string gives an empty string.

Examples

shelf_label(" the little prince ")→'The Little Prince'

shelf_label("MOBY DICK")→'Moby Dick'

main.py

def shelf_label(book):
    # your code here: strip() then title(), and return the result
    return book

Ctrl + Enter runs too
