The maximum number of arguments for any function in Python used to be 255. Since Python 3.7, this limit has been removed.

Another novelty in Python 3.7 is the new module dataclass which simplifies the declaration of a class with multiple arguments.

For example this code:

@dataclass
class InventoryItem:
    '''Class for keeping track of an item in inventory.'''
    name: str
    unit_price: float
    quantity_on_hand: int = 0

    def total_cost(self) -> float:
        return self.unit_price * self.quantity_on_hand

Will add, among other things, a __init__() that looks like:

def __init__(self, name: str, unit_price: float, quantity_on_hand: int=0):
    self.name = name
    self.unit_price = unit_price
    self.quantity_on_hand = quantity_on_hand
