Chain of Responsibility Pattern in Python

class Approver:
    # Chain of Responsibility: offer a request to handlers in order.
    def __init__(self, name, limit, next_approver=None):
        self.name, self.limit, self.next = name, limit, next_approver

    def approve(self, amount):
        # Handle locally or pass the request along the chain.
        if amount <= self.limit:
            return f"{self.name} approved {amount}"
        if self.next:
            return self.next.approve(amount)
        return "Declined"


chain = Approver("Lead", 100, Approver("Manager", 1000))
print(chain.approve(500))
