Python Movie Ticket Booking System: Design, Code Walkthrough, and Usage Guide

This guide demonstrates how to create a functional movie ticket booking application using Python, suitable for beginners learning basic programming concepts, data structures, and object‑oriented design.

Effect Display : The system shows a simple textual interface where users can view available movies and seat maps.

Overall Structure Diagram : An image (not reproduced here) outlines the relationship between four modules – infos.py (movie data), seat_booking.py (seat management), film_selector.py (film selection), and main.py (controller).

Code Breakdown

3.1 infos.py

Movie information is stored as a list of dictionaries, each containing 'name' , 'symbol' (ASCII art), and 'seats' (a 6×8 matrix of '○' for free and '●' for booked seats).

<code>infos = [
  {
    'name': '泰坦尼克号',
    'symbol': '''+==================== 泰坦尼克号 =====================+
    ...
    +===================== Titanic =====================+''',
    'seats': [[...], [...], ...]
  },
  {...},
  ...
]</code>

3.2 seat_booking.py

This module defines the SeatBooking class with methods to display seat status ( check_bookings ), obtain valid row/column input ( get_row , get_col ), book a specific seat ( book_seat ), and automatically reserve the frontmost available seat ( book_seat_at_front ).

<code>class SeatBooking:
    def check_bookings(self, seats):
        print("正在为您查询该场次电影的预订状态...")
        ...
    def get_row(self):
        input_row = input("预订第几排的座位呢？请输入 1～6 之间的数字")
        ...
    def get_col(self):
        input_column = input("预订这一排的第几座呢？请输入 1～8 之间的数字")
        ...
    def book_seat(self, seats):
        while True:
            row = self.get_row()
            column = self.get_col()
            if seats[row][column] == '○':
                seats[row][column] = '●'
                print("预订成功！座位号：{}排{}座".format(row+1, column+1))
                break
            else:
                print("这个座位已经被预订了哦，试试别的吧")
    def book_seat_at_front(self, seats):
        for row in range(6):
            for column in range(8):
                if seats[row][column] == '○':
                    seats[row][column] = '●'
                    print("预订成功！座位号：{}排{}座".format(row+1, column+1))
                    return
        print("非常抱歉🥺，所有座位都被订满了，无法为您保留座位")
</code>

3.3 film_selector.py

The FilmSelector class presents the list of movies, prompts the user to choose a film or exit ( 'x' ), and validates the input.

<code>class FilmSelector:
    def display_options(self, films):
        print("今日影院排片列表：")
        for i in range(len(films)):
            print(f"{i+1} - {films[i]['name']}")
        print('x - 退出')
    def get_choice(self, films):
        valid_choice = [str(i+1) for i in range(len(films))]
        valid_choice.append('x')
        choice = input('你的选择是？')
        while choice not in valid_choice:
            choice = input('没有按照要求输入哦，请重新输入')
        return choice
</code>

3.4 main.py

The Controller class ties everything together: it welcomes the user, lets them select a film, shows the film’s ASCII art, offers two booking methods (specific seat or frontmost seat), and finally says goodbye.

<code>class Controller:
    def __init__(self, infos):
        self.films = infos
        self.welcome()
        self.choose_film()
        if self.choice != 'x':
            self.choose_seat()
        self.bye()
    ...
</code>

Running the script launches an interactive console where users can view movies, see seat maps, and reserve seats, illustrating basic Python I/O, list manipulation, and class‑based design.
