The sign-up sheet has names like "Lee, Ann": family name first, given name after the comma. The badge needs it the other way round: "Ann Lee". Write badge_name(entry) to return the badge name, with any extra spaces around the comma removed.
badge_name("Lee, Ann")→'Ann Lee'badge_name("Garcia,Maria")→'Maria Garcia'def badge_name(entry):
# your code here: split(",") into family and given
# your code here: trim both, join as given then family, and return it
return entry
