Need help sorting a namedtuple and then printing the name of each namedtuple in Python -

hello having difficulty getting function work.

i given list (rl) of restaurants in namedtuples , asked create function sorts list alphabetically order , returns name of each namedtuple. have far

def alphabetical_names(r: restaurant) -> list: '''returns name of restaurants sorted alphabetically '''     restaurants in sorted(r):         return(restaurant.name)  print(alphabetical_names(rl)) 

however when run thing 'property object @ 0x034a4a80>' , don't know why

there number of problems code.

• you have declared r restaurant not list.
• you give variable name for loop plural - confusing.
• most importantly, have referred restaurant class, not instance of restaurant.

try:

def alphabetical_names(r: list) -> list: '''returns name of restaurants sorted alphabetically '''     restaurant in sorted(r):         return(restaurant.name)  print(alphabetical_names(rl)) 

however still has problem, return first result, not list. try:

def alphabetical_names(r: list) -> list: '''returns name of restaurants sorted alphabetically '''     return sorted(r):  print(alphabetical_names(rl)) 

this may not sort entries in order want, possible need provide sorted cmp function change sort order.
