基于Python实现随机点名系统的示例代码

 大家好，我是了不起！

在某些难以抉择得时候，我们经常要用外力来帮助我们做出选择

比如，梁山出征方腊前沙场点兵，挑选先锋的场景

这个时候，有一个随机点名系统就非常好啦，毕竟我水泊梁山的名号~

效果展示

创建一个这样的文件夹，然后把要随机点名的名字写在里面

导入后,这里就显示你导入了多少人员信息

点击开始点名后,会随机从导入名字里挑选一位幸运儿~

效果大概就是这样,下面我们来看看代码吧

导入模块

里面有第三方模块,需要大家自己安装一下

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()

子线程调用

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

应用初始化信息

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

姓名信息布局

????????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)

开始信息布局

????????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)

数据信息布局

????????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)

整体布局

????????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')

运行

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