python制作课堂点名系统，从此老师对我关爱有加

前言

大家早好、午好、晚好吖 ❤ ~

准备工作

首先我们需要准备好点名的姓名文件，使用的时候导入进去就可以开始点名了。

新建一个文本文档，将姓名设置设置好，如下：

使用系统库和第三方库都比较常规

from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *from qdarkstyle import load_stylesheet_pyqt5import os
import sys
import time
import random

代码展示

点名功能实现

class WorkThread(QThread):trigger = pyqtSignal(str)finished = pyqtSignal(bool)def __init__(self, parent=None):super(WorkThread, self).__init__(parent)self.parent = parentself.working = Truedef __del__(self):self.working = Falseself.wait()def run(self):data_list = self.parent.data_listif len(data_list) >= 1:ran = random.randint(20, 40)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')
