解决方案

模拟订票系统需要有以下几个部分组成

一、添加飞机信息

二、删除飞机信息

三、航班信息查询

四、航班信息显示

五、修改飞机数据

六、个人订票

七、个人退票

八、个人订票查询

九、退出系统

以上功能是通过python里面tkinter库实现用户界面和控制按钮的

先定义一个航班类

class Train:  # 定义一个航班类def __init__(self):self.ID = ''self.firstname = ''self.lastname = ''self.time = ''self.price = 0self.seating = 0

再定义一个用户类

class Users:def __init__(self):self.personID = ''self.name = ''self.ID = ''self.time = ''self.seating = 0

打开提前写好的txt文件，里面包含所有的航班信息，按照航班号、起点、终点、起飞时间、票价和剩余票数罗列而得，也可以后期通过“添加飞机信息”模块进行航班信息录入

def Init(trainlist):  # 初始化函数print("初始化......")file_object = open("flight.txt", 'r')for line in file_object:tra = Train()line = line.strip("\n")s = line.split(" ")tra.ID = s[0]#k268tra.firstname = s[1]#起点tra.lastname = s[2]#终点tra.time = s[3]#起飞时间tra.price = s[4]#票价tra.seating = s[5]#剩余票数trainlist.append(tra)file_object.close()man_object = open('man.txt', 'r')for line in man_object:user = Users()line = line.strip("\n")m = line.split(" ")user.personID = m[0]user.name = m[1]user.ID = m[2]user.time = m[3]user.seating = m[4]people.append(user)man_object.close()print("初始化成功！")

下面进入信息管理模块，其中包含添加、删除、查询模块

class ADD:  # 信息录入def Add_f(self):#“添加飞机信息”模块roob = Toplevel(win)roob.title('飞机信息输入')roob.geometry('500x240')lb1 = Label(roob, text='请输入航班号')lb1.place(relx=0.1, rely=0.1, relwidth=0.5, relheight=0.1)a_text = StringVar()a_text.set("")self.inp1 = Entry(roob, textvariable=a_text)self.inp1.place(relx=0.6, rely=0.1, relwidth=0.3, relheight=0.1)lb2 = Label(roob, text='请输入起点')lb2.place(relx=0.1, rely=0.2, relwidth=0.5, relheight=0.1)b_text = StringVar()b_text.set("")self.inp2 = Entry(roob, textvariable=b_text)self.inp2.place(relx=0.6, rely=0.2, relwidth=0.3, relheight=0.1)lb3 = Label(roob, text='请输入终点')lb3.place(relx=0.1, rely=0.3, relwidth=0.5, relheight=0.1)c_text = StringVar()c_text.set("")self.inp3 = Entry(roob, textvariable=c_text)self.inp3.place(relx=0.6, rely=0.3, relwidth=0.3, relheight=0.1)lb4 = Label(roob, text='请输入飞机起飞时间')lb4.place(relx=0.1, rely=0.4, relwidth=0.5, relheight=0.1)d_text = StringVar()d_text.set("")self.inp4 = Entry(roob, textvariable=d_text)self.inp4.place(relx=0.6, rely=0.4, relwidth=0.3, relheight=0.1)lb5 = Label(roob, text='请输入飞机的票价')lb5.place(relx=0.1, rely=0.5, relwidth=0.5, relheight=0.1)e_text = StringVar()e_text.set("")self.inp5 = Entry(roob, textvariable=e_text)self.inp5.place(relx=0.6, rely=0.5, relwidth=0.3, relheight=0.1)lb6 = Label(roob, text='请输入飞机的票数')lb6.place(relx=0.1, rely=0.6, relwidth=0.5, relheight=0.1)f_text = StringVar()f_text.set("")self.inp6 = Entry(roob, textvariable=f_text)self.inp6.place(relx=0.6, rely=0.6, relwidth=0.3, relheight=0.1)self.bt1 = Button(roob, text="清空数据", command=self.Delete)self.bt1.place(relx=0.1, rely=0.9, relwidth=0.1, relheight=0.1)self.bt = Button(roob, text="添加", command=lambda: self.Add(a_text, b_text, c_text, d_text, e_text, f_text))self.bt.place(relx=0.7, rely=0.8, relwidth=0.2, relheight=0.1)self.btClose = Button(roob, text='关闭', command=roob.destroy)self.btClose.place(relx=0.7, rely=0.9, relwidth=0.2, relheight=0.1)self.txt = Text(roob)self.txt.place(relx=0.1, rely=0.8, relwidth=0.4, relheight=0.1)def Delete(self):#“删除飞机信息”模块self.inp1.delete(0, END)self.inp2.delete(0, END)self.inp3.delete(0, END)self.inp4.delete(0, END)self.inp5.delete(0, END)self.inp6.delete(0, END)def Add(self, ID, firstname, lastname, time, price, seating):tra = Train()tra.ID = str(ID.get())tra.firstname = str(firstname.get())tra.lastname = str(lastname.get())tra.time = str(time.get())tra.price = str(price.get())tra.seating = str(seating.get())print(tra.ID, tra.firstname, tra.lastname, tra.time, tra.price, tra.seating)if self.searchByID(trainlist, tra.ID) == True:self.txt.delete(1.0, END)self.txt.insert(END, '航班重复,保存失败')returntrainlist.append(tra)file_object = open("train.txt", "a")file_object.write(tra.ID)file_object.write(" ")file_object.write(tra.firstname)file_object.write(" ")file_object.write(tra.lastname)file_object.write(" ")file_object.write(tra.time)file_object.write(" ")file_object.write(tra.price)file_object.write(" ")file_object.write(tra.seating)file_object.write("\n")file_object.close()self.txt.delete(1.0, END)self.txt.insert(END, '保存成功')returndef searchByID(self, trainlist, ID):#“航班信息查询”for item in trainlist:if item.ID == ID:return Truereturn False

运行效果截图

注意事项：（可能会出现的错误）

一、No such file or directory: 'flight.txt'

这种情况的原因应该是txt文件和py文件不在一个根目录里面

解决办法：把txt文件和py文件放在一个文件夹里面

二、-tkinter.TclError: couldn't recognize data in image file "light.jpg"

这种情况的原因是tkinter库无法识别.jpg格式的文件

解决办法：把jpg换为gif的文件，或者换一个库使用，如PIL库

PS：有些第三方库是只提供源码，具体下载和使用方法放在下一篇文章。
