基於Python怎麼實現隨機點名系統

效果展示

建立一個這樣的資料夾，然後把要隨機點名的名字寫在裡面

導入後,這裡就顯示你導入了多少人員資訊

點擊開始點名後,會隨機從導入名字裡挑選一位幸運兒~

#效果大概就是這樣,下面我們來看看程式碼吧

導入模組

裡面有第三方模組,需要大家自己安裝一下

from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *

from qdarkstyle import load_stylesheet_pyqt5

import os
import sys
import time
import random

class WorkThread(QThread):
    trigger = pyqtSignal(str)
    finished = pyqtSignal(bool)

    def __init__(self, parent=None):
        super(WorkThread, self).__init__(parent)
        self.parent = parent
        self.working = True

    def __del__(self):
        self.working = False
        self.wait()

    def run(self):
        data_list = self.parent.data_list
        if len(data_list) >= 1:
            ran = random.randint(6, 10)
            print('遍历次数：', ran)
            for a in range(ran):
                name = random.choice(data_list)
                self.trigger.emit(name)
                print(name)
                time.sleep(0.6)
            self.finished.emit(True)
        else:
            self.trigger.emit('无数据')


class ClassCollSystem(QWidget):
    def __init__(self):
        super(ClassCollSystem, self).__init__()
        self.data_list = []
        self.init_ui()

子執行緒呼叫

    def init_ui(self):
        self.thread_ = WorkThread(self)
        self.thread_.trigger.connect(self.set_name)
        self.thread_.finished.connect(self.finished)

應用初始化資訊

        self.setWindowTitle('课堂点名系统')
        self.setWindowIcon(QIcon('课堂点名.ico'))
        self.setFixedSize(500, 350)

姓名資訊佈局

        vbox_name = QVBoxLayout()
        self.current_name = QLabel()
        self.current_name.setText('随机点名啦')
        self.current_name.setStyleSheet(
            'font-size:50px;text-align:center;font-weight:bold;font-family:"Microsoft JhengHei";')

        vbox_name.addWidget(self.current_name)
        vbox_name.setAlignment(Qt.AlignCenter)

開始資訊佈局

        vbox_start = QVBoxLayout()
        self.start_btn = QPushButton()
        self.start_btn.setText('开始点名')
        self.start_btn.setFixedSize(160, 50)
        self.start_btn.setStyleSheet(
            'font-size:30px;font-weight:bold;text-align:center;font-family:"Microsoft JhengHei";')
        self.start_btn.clicked.connect(self.start_btn_click)

        vbox_start.addWidget(self.start_btn)
        vbox_start.setAlignment(Qt.AlignCenter)
        vbox_start.addSpacing(80)

資料資訊佈局

        vbox_data = QHBoxLayout()
        self.message = QLabel()
        self.message.setText('信息提示')
        self.message.setStyleSheet(
            'font-size:12px;')

        self.import_btn = QPushButton()
        self.import_btn.setText('导入数据')
        self.import_btn.setFixedSize(90, 25)
        self.import_btn.clicked.connect(self.import_btn_click)

        vbox_data.addWidget(self.message)
        vbox_data.addStretch(1)
        vbox_data.addWidget(self.import_btn)

整體佈局

        vbox = QVBoxLayout()
        vbox.addLayout(vbox_name)
        vbox.addLayout(vbox_start)
        vbox.addLayout(vbox_data)

        self.setLayout(vbox)

    def start_btn_click(self):
        if self.start_btn.text().strip() == '开始点名':
            self.thread_.start()
        else:
            self.start_btn.setText('开始点名')

    def set_name(self, name):
        self.current_name.setText(name)

    def finished(self, finished):
        if finished is True:
            self.start_btn.setText('就是你了')

    def import_btn_click(self):
        file = QFileDialog.getOpenFileName(self, '选择文件', os.getcwd(), 'Text File(*.txt)')
        file_path = file[0]
        print(file_path)
        fl = open(str(file_path), 'r', encoding='utf-8')
        self.data_list = fl.read().strip().split('\n')
        print(self.data_list)
        self.message.setText('信息提示 | 成功导入[' + str(len(self.data_list)) + ']条人员信息')

運行

if __name__ == '__main__':
    app = QApplication(sys.argv)
    app.setStyleSheet(load_stylesheet_pyqt5())
    main = ClassCollSystem()
    main.show()
    sys.exit(app.exec_())
