Python模拟飞机选座系统：实现与扩展功能

Python实现：模拟飞机选座系统

在构建一个飞机选座系统时，我们可以利用Python来模拟一个基本的座位选择功能。此系统将包含座位布局展示、用户选座、重复确认和显示最终选择等功能。以下代码将展示如何实现一个简单的飞机选座系统。

功能描述

座位布局初始化：设定飞机座位布局，如每排有6个座位（A, B, C, D, E, F），总共20排。
显示座位：清晰地展示座位状态（O表示空座位，X表示已占用）。
选择座位：用户可以选择具体的座位。
确认选座：提供选座确认提示，避免误选。
显示最终结果：确认选座后展示更新后的座位布局。

代码实现

class AirplaneSeatingSystem:
    def __init__(self, rows=20, seats_per_row=6):
        self.rows = rows
        self.seats_per_row = seats_per_row
        # 初始化所有座位为空座位 "O"
        self.seats = [['O' for _ in range(seats_per_row)] for _ in range(rows)]
        self.seat_labels = ['A', 'B', 'C', 'D', 'E', 'F'][:seats_per_row]

    def display_seating(self):
        print("\nCurrent seating arrangement:")
        print("   " + " ".join(self.seat_labels))  # 顶部显示座位标签
        for i, row in enumerate(self.seats):
            row_display = f"{i + 1:2} " + " ".join(row)
            print(row_display)
        print("O = Available, X = Occupied\n")

    def select_seat(self, row, seat):
        # 检查行号和座位号是否有效
        if 0 < row <= self.rows and seat in self.seat_labels:
            seat_index = self.seat_labels.index(seat)
            if self.seats[row - 1][seat_index] == 'O':
                confirm = input(f"Confirm booking for seat {row}{seat}? (yes/no): ").strip().lower()
                if confirm == 'yes':
                    # 更新座位状态
                    self.seats[row - 1][seat_index] = 'X'
                    print(f"Seat {row}{seat} successfully booked!")
                else:
                    print("Seat selection cancelled.")
            else:
                print(f"Seat {row}{seat} is already occupied. Please choose another seat.")
        else:
            print("Invalid seat selection. Please try again.")

    def start_booking(self):
        print("Welcome to the Airplane Seating System!")
        while True:
            self.display_seating()
            try:
                row = int(input("Enter the row number (1-20) or '0' to exit: "))
                if row == 0:
                    print("Thank you for using the Airplane Seating System!")
                    break
                seat = input("Enter the seat letter (A-F): ").upper()
                self.select_seat(row, seat)
            except ValueError:
                print("Invalid input. Please enter a valid row number.")

使用流程

初始化程序：创建AirplaneSeatingSystem的实例并开始选座流程。
```
plane = AirplaneSeatingSystem()
plane.start_booking()
```
用户交互：
程序将展示当前座位状态。
用户输入行号和座位字母来选择座位。
系统提供确认选座提示，用户需输入yes或no进行确认。
退出程序：输入0退出选座程序。

示例运行

Welcome to the Airplane Seating System!

Current seating arrangement:
    A B C D E F
 1  O O O O O O
 2  O O O O O O
 ...
20  O O O O O O

O = Available, X = Occupied

Enter the row number (1-20) or '0' to exit: 5
Enter the seat letter (A-F): B
Confirm booking for seat 5B? (yes/no): yes
Seat 5B successfully booked!

Current seating arrangement:
    A B C D E F
 1  O O O O O O
 2  O O O O O O
 3  O O O O O O
 4  O O O O O O
 5  O X O O O O
