5,163 Pointsyou'r code works if a word can be break in exactly 2 peaces like 'word', but if you have a word like 'treehouse' and you do a len('treehouse') / 2 the result will be 4. so your code will print treeOUSE because [-4:] is telling python to print only the las 4 characters from 'treehouse' and [4:] is telling python to print all the characters from the 4th till the end.
