Python模拟银行

以下是Python模拟银行排队系统的代码实现：

import time

class Customer:
    def __init__(self, name, transaction_time):
        self.name = name
        self.transaction_time = transaction_time

def simulate_bank_queue(customers):
    queue = []
    for customer in customers:
        queue.append(customer)
        print("Customer", customer.name, "enters the queue.")
        time.sleep(1)
    print("All customers have entered the queue.")
    time.sleep(1)
    print("Processing customers...")
    while len(queue) > 0:
        customer = queue.pop(0)
        print("Processing customer", customer.name, "...")
        time.sleep(customer.transaction_time)
        print("Customer", customer.name, "has finished the transaction.")
    print("All customers have been processed.")

# 示例
customers = [Customer("A", 5), Customer("B", 3), Customer("C", 2)]
simulate_bank_queue(customers)

该代码实现了一个简单的银行排队系统，包括顾客进入队列、等待和处理过程。其中，`Customer`类表示一个顾客，包括姓名和办理业务所需时间；`simulate_bank_queue`函数接受一个顾客列表作为参数，将顾客依次加入银行队列，然后逐个处理队列中的顾客。
