I was wondering what "capacity" meant. So, if that's just the count, where is the actual linkage between the bank and the memories? Anyway, the Anytone model I'm working on right now is the same (each mem is limited to one bank, or none):

class AnytoneBankModel(chirp_common.BankModel):
    """
    The Anytone bank model, for the radios that support it, is that a memory
    channel can only belong to one bank at a time. There are 10 banks (A-J
    with no alternate names). The mapping is done in a block of bytes that
    correspond to the 750 memories (one byte per memory). The possible values
    are 0-9 (A-J) or 15 (x0F) for "off".
    """
    def __init__(self, radio, name="Banks", num_banks=10, num_memories=750):
        super(AnytoneBankModel, self).__init__(radio, name)
        self._bank_bounds = range(num_banks)
        self._mem_bounds = range(1, num_memories + 1)
        self._banks = [
            chirp_common.Bank(self, i, string.ascii_uppercase[i]) for i in self._bank_bounds
        ]
    def get_num_mappings(self):
        return len(self._banks)
    def get_mappings(self):
        return self._banks
    def add_memory_to_mapping(self, memory, bank):
        self._radio.set_bank(memory.number, bank.get_index())
    def remove_memory_from_mapping(self, memory, mapping):
        self._radio.clr_bank(memory.number)
    def get_mapping_memories(self, bank):
        """Returns a list of all memories assigned to the given bank"""
        memories = []
        for i in self._mem_bounds:
            bank_index = self._radio.get_bank(i)
            if bank_index is not None and bank_index == bank.get_index():
                memories.append(self._radio.get_memory(i))
        return memories
    def get_memory_mappings(self, memory):
        bank_index = self._radio.get_bank(memory.number)
        return [] if bank_index is None else [self._banks[bank_index]]

BTW, "scrabmler_code" is misspelled.

A memory can not be in more than one bank simultaneously.

A memory need not be in a bank.

Memories are stored sequentially starting from [0].  Each number in banks holds the count of memories in that bank.  The count can be 0.  So to find the start index of the first memory in a bank we have to sum the sizes of all previous banks.

I just went through that myself. The first two questions: 1. Can one 
memory belong to multiple banks simultaneously? 2. Does every memory 
have to belong to at least one bank? The answers determine which base 
class you use for the bank model.

You need to implement a bank model so that Chirp can inquire, for 
example, which memories are in bank C?

You also need to implement get_bank(), set_bank(), clear_bank() for a 
memory (in the radio class), which will be called by the bank model.

Hopefully, that's enough to get you started.

Does anyone have an example that will help me understand MemoryMapping, MappingModel, Bank, and BankModel classes?  I’m working on a driver for the Icom IC-F520 land mobile radio.

The F520 has 256 channels and 16 banks.  This is how they look in  MEM_FORMAT:
