[FIXED] Unexpected type(s): (set[Selfcheckout | int]) Possible type(s): (SupportsKeysAndGetItem) (Iterable[tuple[Any, Any]])

Issue

I got a Unexpected type(s): (set\[Selfcheckout | int\]) Possible type(s): (SupportsKeysAndGetItem) (Iterable\[tuple\[Any, Any\]\]) error.

Lane is a normal counter, and Self is a self checkout both have an attribute in the form of queue which is just a list of customers.

I'm trying to sort this list of Lanes and Selfs called openqueues using a dictionary.

I don't really have an idea what to do next, this function is just supported to return the sorted list of lanes basted on their lengths.

def getsortedopen(openqueues):
    sort = []
    dictionary = {}
    if isinstance(openqueues, list):
        for lane in openqueues:
            if isinstance(lane, Lane) | isinstance(lane, Self):
                dictionary.update({lane, len(lane.queue)})
        dictionary = sorted(dictionary.items(), key=lambda x: x[1])
        dictionaryb = dict(dictionary)
        for key in dictionaryb:
            sort.append(key)

Solution

Changes needed:

def getsortedopen(openqueues):
    sort = []
    dictionary = {}
    
    if isinstance(openqueues, list):
        for lane in openqueues:
            if isinstance(lane, Lane) or isinstance(lane, Self):
                dictionary[lane] = len(lane.queue)
        
        # Sorting the dictionary by the length of the queues
        sorted_dict = dict(sorted(dictionary.items(), key=lambda x: x[1]))
        
        # Appending the lanes to the result list
        sort.extend(sorted_dict.keys())
    
    return sort

1. Use or instead of | for logical OR.
2. Use {} to create a dictionary.
3. Simplify the sorting and appending process.
