python3+pyqt5实现简易机票预订系统

一个简易的机票预订系统,填写信息、预定机票、获得取票码、取票/更改机票,还拥有机票查询系统。
以下是完成后的文件目录
python3+pyqt5实现简易机票预订系统_第1张图片
首先创建数据库,可以用代码,也可以用可视化工具(Navicat等等),这里给出代码

import pymysql

conn = pymysql.connect(host='localhost', user='root', passwd='123456', db='bjx', charset='utf8')
cur = conn.cursor()
cur.execute("""CREATE TABLE IF NOT EXISTS informationmessage(
    real_name varchar(10) PRIMARY KEY,
    sex varchar(2),
    work_unit varchar(20),
    id varchar(20),
    travel_time varchar(11),
    start_place varchar(10),
    end_place varchar(10),
    class varchar(5),
    advance varchar(5),
    total_money varchar(5),
    code varchar(7))""")
conn.commit()

cur.execute("""CREATE TABLE IF NOT EXISTS flight(
    flight_number varchar(10) PRIMARY KEY,
    start_place varchar(10),
    end_place varchar(10),
    travel_time varchar(11),
    first_class varchar(4),
    business_class varchar(4),
    economy_class varchar(4),
    count_passenger varchar(4))""")
conn.commit()

完成后可以用可视化工具查看

接下来编写界面

1.预订机票主界面

python3+pyqt5实现简易机票预订系统_第2张图片
界面的图片可自行寻找,放在目录中的picture里,设置在没有预定机票成功之前,预定金交付按钮无法点击,以下是代码

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow1(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(908, 474)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(720, 60, 121, 41))
        self.pushButton.setObjectName("pushButton")
        self.pushButton_2 = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton_2.setGeometry(QtCore.QRect(720, 170, 121, 41))
        self.pushButton_2.setObjectName("pushButton_2")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(0, 0, 701, 441))

        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 908, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "预定机票"))
        self.pushButton_2.setText(_translate("MainWindow", "预订金交付"))

        self.label_3 = QtWidgets.QLabel(Form)
        self.label_3.setGeometry(QtCore.QRect(170, 40, 21, 21))
        self.label_3.setObjectName("label_3")

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))

        self.label_2.setText(_translate("Form", "money"))
        self.label_3.setText(_translate("Form", "元"))
