When signing up for a game, people sometimes type extra spaces or mix up capitals. Write clean_username(name) to remove the spaces at both ends and return it all in lower case.
clean_username(" Mia_2 ")→'mia_2'clean_username("LEO")→'leo'def clean_username(name):
# your code here: trim both ends, make it lower case
return name
Run tries the examples. When they look right, Submit.
